No order. Gonna do the best or best two from each franchise so it's my top 10 franchises in a way.
Fallout 1/Fallout New Vegas
Shadow of the Colossus
Starcraft (with or without Brood War)
Halo Combat Evolved
Doom II/Doom (2016)
Mortal Kombat III/Mortal Kombat (2011)
Spider-Man 2
Pokemon Gold/Silver/Crystal (I can't stand grinding now-a-days but when I was a kid, these were the best Pokemon games)
I don't know what else
I guess Witcher 1 and both Wastelands? I really enjoyed those.
Planescape Torment isn't on my list but I foresee it happening, I've yet to play it but after I'm done with the Witcher series and maybe Tyranny I'll sit down and finally play it.
