What are some games you find yourself frequently coming back to?
I was going to say replaying but I feel like that limits the question to games like Prey or Fallout New Vegas that have endings and games like The Sims 2 or Cities Skylines where you can play indefinitely end up excluded.
I'm not really referring to games like League of Legends where you're coming back every month. More so games where you stop playing for an extended period of time.
Metal Gear Solid V (on PC with mods that greatly expand/enhance free roam, and add more side ops)
Tomba 1 and 2 (Tombi in the EU)
Chrono Trigger
Megaman Legends (love the sequel, but haven't ever completed it, life keeps getting in the way)
Castlevania Syphony of the Night
Sonic Adventure (it's trash, but fun trash, especially with mods)
Sonic Mania, Sonic 3 and Knuckles
Minecraft
Some that I haven't come back to in a while, but I'm overdue:
Ape Escape
Crash Bandicoot (1-3)
Spyro (1-3)
Digimon World 3
Any of the GBA or DS Castlevanias
Actraiser
Rayman 2
Megaman Battle Network series(3 and 4 are my favorite entries)
Dissidia Duodecim
Zone of the Enders 2
God Hand
Wipeout Pulse/Pure
Pretty much any Kirby game
Most of these games I find just plain fun. Thanks for asking, I was starting to get burned out and not finding stuff as fun, but writing this out has me hankering to revisit some old favorites again.
