ok, ok. you ratted me out. [by the way: first post since i returned from holiday]
the truth is that in time and after playing it through for about the 19th time, TRON 2.0 just didn't really satisfy me any more. it got...well...predictable, then things like doom 3 and half life 2 came along i thought i'd better play half life 1 first, that was amazing from the word go. Half life 2 was even better, and doom 3 was a graphical heaven in hell.
also, all of those games on the list [apart from FFX] are very, very moddable, and new content is always being created for them, which adds more entertainment to it. if this had happened to TRON 2.0, believe me, it would be right at the top of the list, but alas, the community never took off, tron 2.0 was destined to stay as tron 2.0
you've opened my eyes. i'll put it on there, but now it's just something i'll play for a quick burst of entertainment. sadly, that's all it is now.
there's my 'splaination, the sad, sad truth.
