>>49562970MineCraft definitely. Try comfy single-player games that you just felt too alone to finish or grind but love. MMORPGs solo are fine too.
Splatoon, Girls' Frontline modded Call of Duty. Kancolle modded Left4Dead2. Team Fortress.
nostalgia sells from my experience, and it doubles for access to inviting your friends/viewers to play with you. You'll never go pub-lobby teamkill trolled again basically.
