@Frindis Sounds like you completed Diablo 3 to me. I'm guessing everyone who says they completed The Witcher 3's main quest for example probably hasn't cleared out every single question mark on the map?
@Oussebon I really enjoyed my time in Skyrim. I started off the game not fast travelling, just walking out into the wilderness to wherever I hadnt been before. At some point I'd maxed levels on everything I was interested in, made all the best weapons and armor and nothing in the world was a threat. I wonder then at that point what kept you playing, for like 650 hours more? Genuinely curious, because I know you're not the only one
Looking back over everyone's answers so far it seems this was a slightly confusing question to some. Perhaps having something to do with my age (38) I've always had a clear idea about when a game is 'completed'.
To me in simplest terms, If I saw the credits, if I have an achievement that says finished the game on normal/hard/whatever, If I killed the main boss, I've completed it. DLC's, side missions are extras. In a 4X game it means I've won a campaign with at least one faction usually on normal difficulty or higher. None of this means to say that I'm
finished with the game though!
Its highlighted to myself that maybe I'm a strange kind of gamer. I play almost exclusively single player games across almost all genres. I very rarely play through a game more than once. More often than not I'm slightly bored of what I'm currently playing by late game, and if its possible to beeline to the end I often will. I also mostly have no qualms dropping a game if it isn't fun and leaving it half finished.
There's a lot more I could say, but I'll try not to ramble on (
more). Its been interesting so far. Thanks!
