There is a $70 version and an $80 version. And while I agree mostly with the sentiment that companies shouldn't expect $70-80 for games, that is mostly limited to big publicly traded companies that fill these full priced games with microtransaction gotcha garbage.
However, this is Larian Studios we are talking about. They are a private company that self publishes and this game has no bullshit in it. It's a full priced title for a metric fuck ton of content. It's a game made with tremendous love and care and attention to detail. It's a game not maximized for profit, but for fun and player creativity. Games like this just don't get made anymore and the soaring review scores speak volumes as to the quality of this game.
I can understand if you can't afford it on your current budget, but this is not a game to make an example out of. Boycott $80 COD, boycott F2P and P2W, boycott EA, boycott Ubisoft, but don't lump Larian in with their ilk.
