In general, Firaxis makes strategy games, not event generators
Paradox games are overrated trash, honestly. I have stopped pirating anything they produce (let alone paying for...), cause they all suck. Not even worth the few GBs to torrent, and i have a 100MB/s line. I pitty the Stockholm syndrome people who buy their shit thinking they are playing some sophisticated strategy while all they are doing is wasting time on pathetic messes that play themselves. There are many issues with that company, and while many cry about their DLC policies, i think this is one of the most insignificant things to complain about. As i said, not even worth pirating, and when pirating DLCs are free. The real issues with their games lie elsewhere, and i don't see them improving their shit any time soon. Even if they do try, like in the case of Stellaris (initial release) or Imperator Rome (initial release), their fans will still complain, cause when a faggot is used to getting fucked in the ass, he is going to take it personally if you stop raping him all of a sudden, he will think that something went wrong, that you don't love him anymore. I won't go into detail about what i mean, but just say that their older games had gameplay that sucked hard, and games like Stellaris and Imperator were attempts to make something actually worthwhile, but since this alienated their hardcore fags, they decided to do a 180o and patch those games to become the same shit as EUIV. Cause of course they would.
Still, having said that, claiming that Firaxis making strategy games while Paradox does not, is a fucking lie. Firaxis makes GARBAGE, literally. There is no strategy involved in Civ VI or Xcom 2. Those games play themselves. There is basically one correct way to play them, and you are just trained by trial and error to act like it, or fail. There is also tons of bad RNG and other shit.
Basically, i refuse to get anything new from both companies these days. They both suck and produce overhyped/overrated trash. If you want 4X, there are other companies, more indy, but produce better shit, like Slitherine or Aptitude/SEGA. If you want tactics, you are better of playing a Larian game (LOL) than their shit. "Grand strategy" my ass. Those are just risk simulators with real world names and a bunch of buttons and sliders to make you think you are controlling the simulation, but only just a bit. LOL.
