Estimates have put the game's budget at upwards of $250 million, so they'd need to sell at least 5 times as many copies to even break even. Games (from traditional studios, anyway) are crazy expensive now.
No you're not. You're allowed to hope for something and be let down it's on them to do better especially since they can and have the resources to do so but choose not to.
I just got it on sale ($15 off on Uplay) and I gotta say I'm rather confused why it isn't more popular. It's not perfect, and combat is a little simple, but it's exceptionally well written, the mini games are legit fun, and the world feels really fleshed out and authentic and the music is outstanding. The main theme sounds like a modern take on Williams it's crazy good.
Tbh I haven't even noticed the "AI" generated stuff it's no different than procedurally generated content if not even more well weaved in the game. I dunno it's just fun for me. Just change the settings to all hard and disable the assists and suggestions.
