Performance bottleneck is a big issue, specially when you consider the level of graphics and AI in games these days. It is insanely clever, and would require parts of your game to be tuned in hand coded assembly, most games developers regularly hand code AI in inline assembly. The low level thinking is perfectly right, Games like mario,contra and others were even possible on a 8 bit machine with sound and graphics game loop and some AI because of assembly. Abstraction is good but not always. At some places you have to do a tradeoff. Also try writing a GLSL shader in java and then in Obj-C,C or C++ you will know how much better the latter are. This is why abstraction is not a good thing always. Lisp is great i too agree even i like lisp very much, but a large part of the documentation available for Obj-C/Cocoa/Cocoa-touch is for Obj-C. That too apples documentation on the language and framework is the best available on the internet. Also Obj-C is a great language it is very similar to smalltalk and if you know smalltalk, Obj-C would be a joy to program in. Infact i felt Obj-C to be very similar to ruby conceptually.
