Games you can always come back to

[Zenryu]

for me it would be
Ratchet and Clank series
Jak and daxter series
Tales of Vesperia
Halo 1-3
Black Ops 1 Zombies
original Battlefront 2

I'm sure there are more that i'm not thinking about right now.

Honestly for me it's Borderlands 2. I feel that (so far at least!) the 2nd game in the series does EVERYTHING right, and comes together to make an amazing experience. I've played through the "story" over 15 times now, which isn't THAT much when compared to "REAL" BL2 players, but... what makes Borderlands different is that it's never boring. Each playthrough offers a different experience, enemies get harder, loot drops are better, you get a higher level, etc. Not to mention the DLCs... By far some of the best DLCs of any game ever made, and you can get the GOTY edition, including a WHOLE lotta DLCs, for maybe $5 on one of the 50 times it's on sale a year.

great now i wanna stop playing smash and go relive some good old memories XD

[True Sight]

The first time I replayed it was probably 8 years after I first played it. The only thing I noticed was how awful I was at additions the first time and how much easier the game was if I didn't suck at the button combos

[TPyro]

man, i really want to play legend of the dragoon again as its crossed my mind so many times, but i feel as though my memories of it are on a higher pedestal and playing it now would crush that. Great picks btw

[Dean Gillburry]

Shining Force 1 & 2, Final Fight, River City Ransom, Morrowind

[True Sight]

2 games I've always gone back and replayed and enjoyed almost as much as the first time through would be legend of dragoon and ffx. I think it might be mostly nostalgia from when I was a kid but love those games.
