Guerilla Games has one, maybe two (if we're generous) really good games. Certainly, we aren't arguing that Killzone Shadowfall is anywhere near the level of Breath of the Wild or The Last of Us.
GG only literally needed writing, and some better animation tech, in their games to make them succeed. They have that now. There is no going back. They are unarguably a top tier studio in my book.
Then we have a very loose definition of "great," then. I can think of dozens of games I prefer to Horizon, but I'd hesitate to say Capcom is on par with EAD because of RE4, or that Obsidian is on par with Naught Dog because of New Vegas.
Like, Guerilla's last game was Killzone Shadowfall, which was a mediocre 5/10 game if I've ever seen one. Their last particularly good game came out in 2009. To compare that to developers that companies that put out multiple 10/10 games a generation is laughable.
Their tech is leagues ahead of anything any Nintendo developer is even attempting to do. They have traded blows with 2 devs in Sony's stable for the most advanced graphics tech out there. Capcom has never competed with them and neither has Obsidian ever come close to equaling the tech that GG produces. They may have a few great games for sure, but nothing that stands out as a 10/10.
So you are basically comparing writing and storyline at this point. This is where you sound laughably inane in thinking somehow GG is not top tier.
All they needed was someone to write a story, to help them fill in the blanks, and they have that now.
You can basically mark it down that their next game will be amazing. You don't go backwards after this lol. GG is a highly competent developer.
KZSF was more like a 7/10 game with bad writing in my book. There were at least 3 great levels in that game.
Also, when the hell did any of those devs EVER put out a 10/10 game lol.
Even with mods I fell asleep during Fallout New Vegas. The game world was like a miniature lego set. Capcom has sucked balls since RE4. I literally have no idea what you are even trying to suggest. There is not one 10/10 game in any of the stables of these devs. Not even close.
