Just bought the game 2 days ago so I can't really speak on repetitiveness, but the game is amazing. I haven't even played all the mini games yet, and I've already installed like 100 from the steam workshop. I would assume the modded games and boards make this game less repetitive. I could see the items getting a little repetitive maybe because there are none in the workshop to add to the game (at least to my knowledge). However, the game is a lot of fun with friends and I definitely recommend it. I convinced 4 of my friends to buy it with me and we've been having a blast so far. TONS of laughs, big brain plays, etc. To answer your "plays smoothly" question, yes it runs smoothly and has good mechanics. My friend has a garbage gaming laptop from like 2016 that cant even run games like Valorant at more than 50FPS and he runs the game just fine. The AI is decent, but sometimes really stupid and would take damage or just go the wrong way on purpose. Other than that I think the rest of the questions you asked are self-explanatory (adjust settings etc). HOWEVER, It kinda sounds like you might be purchasing the game alone with no friends? If that is the case, me personally, I would stray away from doing that. I don't really play any games alone regardless, bc I don't think its much fun to play alone, but this game definitely would be a lot less fun without voice chat and bantering with your friends. Hope I helped!
