Coming up on 1700 hours (30 hours in the past two weeks). Didn’t even install mods until after like 1200 hours? I don’t think there’s an upper limit to how many times you can replay it, especially since they keep making major updates (when I first played it, Golem was the final main boss and Duke Fishron was a sideboss - 1.1 I think?). Surely the next final update will really be the actual final update and definitely no chance of it ending up as a 1.5.
But I get why it can be a bit of a hard sell without large sales given the graphics make it look dated and the only way to appreciate how much the base game has to offer requires playing at least 10’s of hours, if not 100’s.
I think I got it first on PS+, but now have it on PS Vita, PS3, PS4, Switch, and PC. I haven’t tried mods yet, but I’ll get around to calamity at some point. I was not wanting to deal with them, but I tried them with Stardew Valley and enjoyed them a lot. So, I’m actually really interested, but have largely been playing on the Switch lately.
