Ha, I went thru that too a while ago.
Finished playing Summon Night Swordcraft Story GBA, playing Ghost Trick Phantom Detective NDS, and started yet again Final Fantasy IV this time on the GBA, all emulated in my Android phone thanks to Lemuroid.
Also started playing Resident Evil 3 PSX on my Android tablet (also Lemuroid).
I haven't seen this posted here, but it brings back memories.
Basically Loopy in Simon Tatham's Puzzles, available on Linux, Windows, and Android (F-Droid), when I don't want to be stressed.
Otherwise I just play some retro/old school games like Final Fantasy (started IV a few days ago), (Free)Doom, AssaultCube or Cave Story when on my laptop.
