MMORPG
Persistent online worlds with deep character progression and social systems.
Genre convention: World of WarcraftBlizzard-style game development services
Building MMORPGs, hero shooters, ARPGs and strategy games with the depth, polish and live-service longevity that Blizzard Entertainment's games are known for — deep progression systems, strong art direction, and worlds designed to keep players coming back for years, not months.
Independence note: Fulminous Software is an independent game development studio. We are not affiliated with, sponsored by, or endorsed by Blizzard Entertainment, Activision Blizzard, or Microsoft. References to Blizzard's games (World of Warcraft, Overwatch, Diablo, StarCraft, Hearthstone) describe a genre and quality benchmark clients ask us to build toward — nothing on this page implies a partnership.
What "Blizzard-style" actually means for a build
When clients ask for a game "like Blizzard makes," they're rarely describing one specific feature — they mean a bar of quality and a set of design habits: deep, satisfying progression systems; art direction distinctive enough to be recognisable in a screenshot; lore and world-building that gives every mechanic a reason to exist; and multiplayer or live-service structures built to hold a player base for years through seasons and expansions rather than a single launch window. That's a genuinely different brief from a casual mobile game, and it changes almost every early decision — engine choice, backend architecture, and how much of the budget goes into content pipeline versus core systems.
- Deep progression and itemisation systems that reward long-term play
- Distinctive, cohesive art direction rather than a generic asset-store look
- World-building and lore that gives mechanical systems narrative weight
- Live-service architecture built for seasons, expansions and ongoing content
- Multiplayer systems — PvP, PvE or both — built to scale with a growing player base
Our AAA-style game development services
Each of these covers a genre convention Blizzard-style games are known for — built with the same intent, using your own IP and creative direction.

Custom to your briefCost of building a Blizzard-style game
Indicative GBP pricing by genre and scope. AAA-quality, live-service games carry materially higher budgets than a casual mobile title — here's roughly why.
| Genre / scope | What drives the cost | Estimated cost | Timeline |
|---|---|---|---|
| ARPG (single-player or co-op) | Itemisation, loot systems, combat feel, moderate content volume | £80,000 – £300,000+ | 9–18 months |
| Hero shooter (PvP multiplayer) | Netcode, matchmaking, character balance, anti-cheat, live-ops backend | £150,000 – £500,000+ | 12–24 months |
| RTS / strategy title | Unit AI, pathfinding, balance tuning, campaign or skirmish content | £100,000 – £400,000+ | 10–20 months |
| MMORPG (persistent world) | Server architecture, persistent world state, social systems, ongoing content pipeline | £300,000 – £1,000,000+ | 18–36 months |
| Live-ops & seasonal support | Ongoing content drops, balance patches, event tooling, community management support | £3,000 – £20,000+/month | Ongoing after launch |
These ranges reflect the genuine scope of AAA-style, live-service development — projects at this level are rarely fixed-price from day one. Contact Fulminous Software for a scoping conversation and a realistic, phased budget for your specific concept.

Genre-literate team
Developers who understand why these genres work, not just how to implement individual features.
Live-service experience

Engine flexibility
Unreal Engine 5 for maximum visual fidelity, or Unity where cross-platform reach matters more.

Transparent GBP pricing
Itemised, phase-by-phase costs agreed before each stage of work begins.
Blizzard-style game development FAQs
Are you affiliated with Blizzard Entertainment?
No. Fulminous Software is an independent studio with no affiliation, sponsorship, partnership or endorsement relationship with Blizzard Entertainment, Activision Blizzard, or Microsoft. "Blizzard-style" refers to a genre and quality benchmark, not a business relationship.
What does "Blizzard-style" mean if you're not affiliated with them?
It describes the design habits their games are known for — deep progression systems, distinctive art direction, strong world-building, and live-service longevity — as a reference point for the quality and genre conventions a client is asking for, built entirely around your own IP and creative direction.
Unreal Engine or Unity — which is right for my game?
Unreal Engine 5 typically suits projects where visual fidelity is the priority — cinematic ARPGs or hero shooters, for example. Unity often suits projects that need broad cross-platform reach or faster iteration. We'll recommend based on your specific genre and platform targets; see our Unity 3D game development service for more on that side specifically.
How much does an MMORPG or hero shooter cost to build?
Significantly more than a casual mobile game — an MMORPG typically starts around £300,000 given persistent server architecture and ongoing content needs, while a hero shooter with proper netcode and matchmaking typically starts around £150,000. See the pricing table above for a full breakdown by genre.
How long does a project like this take?
AAA-style, live-service games typically take 9 months at the low end (a focused ARPG) up to 18–36 months for a full MMORPG. We build in staged milestones with a playable vertical slice early on, rather than one long production cycle with nothing to see until the end.
Do you support the game after launch?
Yes — live-service games need ongoing support by design. We provide seasonal content development, balance patching and live-ops infrastructure support through flexible monthly engagements after launch.
