The vast majority of my Steam/GOG library. In fact, I've noticed an uncomfortable trend in the fact that I don't play games that I've actually BOUGHT nearly as much as games I emulate or obtained for free. I bought Project Zomboid to play with aquantance of mine, but haven't touched it, yet I played Graveyard Keeper for nearly 30 hours after it went free to promote the sequel.
Not that anything appears to be set in stone.
However, I also pirated Dragon Ball Sparking Zero, Gundam Breaker 4, and a couple of other games off of Fitgirl, and I haven't played them more than five minutes. Though, I've also played Dragon Ball Heroes: World Mission for around 200 hours and I have near 300 hours in Master Duel (played since launch, not counting combined hours on PS4), so I suppose I just really like card games. I got Yu-Gi-Oh! The Early Days Collection and played everything off of there a whole bunch, and I wasted way to much time screwing around with GX The Beginning of Destiny via OPL but only 50-60 hours on games like RE4HD (not counting PS2, Gamecube or Wii versions), Blood Fresh Supply, Killer Instinct (2013), Super Robot Wars 30, Monster Sanctuary, Vampire Survivor, Jurassic Park: Evolution etc.
I'm not even sure if there is a pattern for any of all this. I started posting on her in December to try and get some advice on how to spend some game cards I was gifted for Christmas and I ended up getting Double Dragon Gaiden, Devil May Cry II: Special Edition (like RE4 I've got this game on almost everything too, like an all day sucker) and Shin Megami Tensai V: Vengeance. I have not touched Vengeance, but I got addicted to grinding for Tokens in Double Dragon Gaiden, and I ended up grinding all of the styles to Lvl3 in DMC3:SE (something I haven't bothered to do on any other version of the game I played thus far).
I there something wrong with me Doc?
