The Best Game Engines
SlappingOysters writes "IGN has taken a look at the most impressive middleware solutions for the next generation of gaming, giving a detailed analysis of which engines are performing the best and which have the most exciting futures. It runs through the technical strengths of each engine, as well as how that translates into actual gameplay. It also runs through which software has and will be using each engine."
Or it might not.
I get your point that using a 3rd party engine would seem to limit your creativity: you wouldn't want to use an engine designed for a FPS to write Battleship Frisbee Cookoff Challenge.
However, if you're intending to create a game that's even remotely within a common genre, then using a 3rd party engine frees you up to concentrate on producing a unique experience. You can blow 20 man years just to catch up with the last generation of Quake, or you can start with a working, tested engine and concentrate your resources on adding just the new functionality and tools that you need.
Why, yes, I'm speaking from experience (of doing it the wrong way). Thanks for asking!
If you were blocking sigs, you wouldn't have to read this.
It's not every day I come across a perfectly good excuse to toot my own horn. Here is my list of free game engines: http://www.freegameengines.org/ My definition of "game engine" is a bit stricter than most. I believe Wikipedia has a similar list.
Drivel like this article is why I quit Slashdot. You can quit too! with only occasional relapses.
