For me it’s Diablo II. Granted I’ve played my fair share of D2 since launch, and also recently on a private server with a comrade from hexbear, but I still feel like years later the game didn’t grab me as much as D1 did.
Granted I don’t hate D2, but for a game that I keep coming back to, D1 takes the prize.
I really hope that they find some synthesis between the BOTW formula and the classic Zelda formula, TOTK was really disappointing on that front and I don’t want 3D and 2D Zelda to remain schism’d in terms of design the way they currently are.
