I have a lot of games that I'll have to finish, but currently, I'm more into replaying
Oddworld: Abe's Exoddus, one of the games that have fucking marked my childhood (I'm mainly a PlayStation guy), didn't play it for almost 20 fucking years (I've lended my 'childhood" copy on a fine day of 2004 and never saw it again) and it's as great as I remembered it. A fucking masterpiece like
Abe's Odyssey.
Regarding the games that I'm determined to finish one day:
There are also some racing (some
Formula Ones,
TOCAs,
Gran Turismos) and fighting games (some
Tekkens,
SoulCaliburs and
Marvel vs Capcoms) that are far from complete, but I don't really count them.
I've spent a lot of time on games like
The Elder Scrolls IV: Oblivion,
The Elder Scrolls V: Skyrim and
Fallout: New Vegas but I don't really play them with the goal of finishing them (Do they really end to begin with?), I just fucking love exploring areas.
