The Blogosphere is a wonderful place sometimes. You'll often see people putting down their thoughts for all to see, but occasionally you'll get a gem from a game developer that gives a bit of raw insight into the games business. Such is the case with Lani, who apparently is working on the UE2.5-powered MMORPG, The Chronicles of Spellborn. Inside, he debunks the perception that Unreal Engine is only good for FPS games:
That's 8 successfully launched MMO's made with the Unreal Engine and at least two of the three forthcoming launches will see the light of day I'm sure (the latter two). I don't know much about Mortal Online and Huxley is well, Huxley. Stargate Worlds is the game that probably won't see the light of day. All because Cheyenne Mountain Entertainment chose the Unreal Engine according to mister 'X'.
But remember, for each MMO project that sees launch there's nine others that don't. That's 72 MMO's not using the Unreal Engine and failed. Statistically speaking you have a better chance at launching using the Unreal Engine than if you built your own from scratch. And there's a reason for that; Not using middleware, also known as trying to re-invent all the wheels on your cart, is a much higher risk than making use of a licensed engine, or two.
