Trine 5 was probably the best Trine to date. It‘s almost a year old, but already discounted to 15ish bucks in sales. Took a friend and I 20 hours to platinum and we had so much fun cheesing the puzzles and doing stupid stuff. I wish there just was no combat in the game tbh, it‘s just there to gatekeep you from having fun with the puzzles lol. I also wish there had been more achievements related to playing a level in a specific way that you gotta figure out. There‘s one for crossing all rivers in a specific map without touching water, and one where you gotta beat any map without destroying boxes. These two were a lotta fun to do.
I was also obsessed with HITMAN (Jan 2022 according to Steam, was a year exclusive to EGS IIRC). Now it‘s just some crappy liveservice-esque thing, but when they actually did new maps and stuff I had tons of fun walking around the crazy detailed levels and looking for small npc skits the devs put in there, doing looney toons banana peel assassinations etc. Agent 47 being that unfeeling killing robot trying to destroy the world controlling illuminati makes all the slapstick so much funnier.
