Then prove it.
Make your own game.
believe me:
Critising what someone else has done is a LOT easier then actually fixing what is wrong in your opinion. I should know. 6 months ago I told a company to bin a 5 year project (made by students on the same type of internship I was there to extend that program). Now that I've graduated they've hired me to make the replacement program. Since then I've discovered that making a program is easy, making a decent program is hard, making a good program is really though (mostly due to inexperience in the language).
Oh well at least I am putting my money where my mouth is (or was).
