Games that I bought years ago and have yet to play:
Atelier Iris 2: I have started it at least 3 times. I would play a bit then a new game came out and then I'd want to restart because I had no idea what was going on anymore. Then my fat PS3 died and I haven't been able to play it.
Atelier Iris 3: I got it cheap, forgot that the reason I originally passed on it was that it had a time limit for dungeons etc. I have never even started it up, probably unopened unless I got it used. I can't remember.
Eternal Poison: I got it because I loved the art and music, and it came with an art book/cd. Sadly I never played more than the first level or two. It was honestly the shittiest TRPG I had ever witnessed. EVERY enemy had multiple uses for its corpse, and you couldn't replay battles. So you basically needed to play through the whole game 7 or 8 times in order to get everything, and HOW and WHO and WHEN you kill ANYTHING is precisely considered or you will screw yourself.
It was like I was trying to get Paragon on Vandal Hearts, or playing Kartia, only without the redeeming qualities of either.
Final Fantasy Crystal Defenders: I just never really played this much. I kinda suck at at it after the first few levels. Which is odd because I rock at Plants vs Zombies.
R-Types/R-Type Delta: I loved and 100%ed R-Type Final with pretty much every ship, but I really suck at RT 1 and 2, and the graphics in Delta made it really hard to see the little bullets. I was constantly dying from crap that the shitty pixilated, low poly, low res, crap textured garbage made all but invisible.
