I got a XP PC for playing Sims 2 and 3, especially 3 is such a mess that it don't really work on anything else, even if it kinda runs.. Also some Lego games and such I used to play as a kid. Well, anything XP era runs, obviously. Just stick/disc it in.
Now I have been cleaning my PS3 (stolen from an ex, added in a bigger SSD) and buying some used games on it from trift stores, for about 2-3€ a piece.. Looking forward for playing that new (for me) GTA! (IV) We also have like.. two PS1s and at least two PS2s. I also still have my PS4, but gonna sell that once I get around. I need money for my offline Linux PC project.. Chose a case that requires a single-slot GPU, send prayers and so on.
