I've got all of the collection installed and my game is very heavily Modded so I can enjoy playing it without losing saves like I used to before getting Mods into the game.I've been playing it since about 2012 and still love it though I had trouble with live mod play until I got Mods to fix the issues that kept ruining my saves if not corrupting them.
It's great if you use a Mod to disable the social workers so they don't take children away as that's known to cause save corruption and is how I lost three saves.I've not lost any saves other than ones where the storyline was finished after Modding my game out.I do also play TS2 style rotationally in empty custom worlds which prolongs my saves as I won't have routing issues and it won't throw EC12's if the world isn't rapidly overloaded with too many sims too quickly.
