I agree.
Don't get me wrong, i am a big fan of complex games. I don't think games are too complex per se, just too complex for me to jump in at a later date. I will play a strategy game at release, but there is ZERO chance i would start playing Stellaris now. Would definitely play a sequel though. Same is true for multiplayer games. I love GaaS, i played Hots and when that died i would have like to keep playing a moba but dota and league have had so much stuff added over the years that i'm just not willing to spend 6 months just to learn the game.
I dont think games should change. Because when i play a game like that i absolutely love the constant content, but yeah, as an outsider, it sucks imo.
I just hate the process of learning new games in general. Even when i know i'd love a game, if i know the process of learning it is too time consuming, i just cant bother.
