Roller Coaster Tycoon 3
Roller Coaster Tycoon (the original)
The Sims 4 (I bought it during a sale for a good price)
Creativerse (sometimes)
Cities: Skylines
Mobile/Facebook games
Dragons: Rise of Berk
Disney Magic Kingdoms (it's pretty good, for a mobile game- and has nice soundtrack in the background)
School of Dragons (I stopped playing because, despite good gameplay, the bugs aren't resolved- happy I never spent Real money on it)
Forge of Empires
Most of the mobile ones are ones I play when I'm looking for a distraction from watching TV, when I'm not writing fiction or feeling creative.
