Just finished fallout sonora.
It was a great experience, definitely the best classic fallout mod out of the ones I've played and genuinely feels like it could be an official game. Its way more polished than the devs previous mod nevada.
All the different factions are great and I liked that there were no cartoonishly evil groups for the most part. There's definitely groups you could call the bad guys but everyone has understandable motivations that feel believable for the fallout setting.
Gameplay felt really well balanced, all the weapon types got good upgrades throughout the game and all skills seemed well supported too. I tagged repair and doctor and they were super useful throughout the whole game.

I highly recommend it for anyone who has already beat fallout 1 and 2.
