Minecraft has become huge and is everywhere, yet the fact is, I don't want to play it anymore.
Portal 2 I would replay any day. I first voted for Dark Souls, yet upon further reflection, Portal 2 is the more perfect timeless game I can pick up and play any time and have a smile on my face in a few minutes. That's ultimately more worthy of goty for me than how much a game positively or negatively influenced the gaming landscape. Because honestly, souls like is more like a stain on the industry to me than a positive. Since it mostly means difficulty for the sake of difficulty, not intricate vertical map design and world building which is what I love Dark Souls for. Same as TotK trying too hard to be Minecraft, is what ultimately makes me prefer BotW.
Once VR gets a big enough install base, Portal 3 made for VR please, just like HL Alyx.
