Non-linearity in my opinion makes games better.

[vlad321]

Because non-linearity the definition of a video game... the ability for YOU to control what happens.

Linear games are just shit movies, basically and I can't think of a SINGLE great linear game. Not one. Although I can see an argument that Half-Life or Mario (NSMBW) are linear, weak one but it exists.

Also, non-linearity doesn't mean a game is good.

Finally, I don't buy your Mass Effect linearity argument one bit. The rest are spot on.
