Agreed, one thing I always reply when people ask about what language, middleware to use, I always give the non-answer of using whatever people are confortable with.

Minecraft would probably never have happened, if Notch started by asking in the forums if he should use Java or not.

Likewise many 8 and 16 bit titles started as BASIC, C, Pascal prototypes before being rewritten into Assembly, after their concept was proven, or thrown away before too much was invested into them.

Discussing what languages, middleware, API, whatever, instead of actually designing the game is what slows development down.
