Warcraft 3+TFT I’ve played the campaigns at least 4 times over the years, I think plus a ton of custom maps plus of course dota 1. Definitely best bang for buck. Other games that are close are path of exile(1k hours), counter strike(800hrs), dota2(1.4k hrs) and wow (way too many hours…but also a lot more money over the years)
For more traditional/offline games:
Gothic 2 I’ve played at least 3 times over the years , I think. Probably have 400+ hours in it. If they remake it like they did with the first one, I’m definitely gonna replay it.
Mass effect trilogy. Played the whole trilogy 3 times and I got the legendary edition but my first playthrough of that is on hold for now.
Don’t remember which number exactly, but one of the older football manager games. I probably have like 400+ hours in that.
Worst value for money? That Warcraft mobile game. For whatever reason I was stupid enough to spend a bunch on it when it came out before I realized how grindy and stupid and pointless it was.
I also have only 22 hours in stalker2 ATM even tho I got it when it came out. It was quite buggy so I figured I’d let them cook some more. I’m sure I’ll get my money’s worth out of it eventually.
Nowadays it’s probably better to start with the gothic 1 remake that came out like a month ago. Either that or drova:forsaken kin which, while unrelated, was heavily inspired by the gothic series.
As for gothic 2… it’s an old game so it’s definitely a bit dated. If you don’t mind old graphics and a slightly harder combat system, I’d still recommend it, tbh. Especially since you can often buy it for 2-5€ during sales.
The first game isn’t required to play. Main character has amnesia after having an accident so everyone you meet that was in the first game will understand if you don’t remember them anymore and will simply explain what happened. So only drawback is that you’ll get minor spoilers regarding the ending of the first game. Not a huge deal, imo, but to each their own.
