For the lesser known titles like Assault Heroes, Rocket Riot, Sam & Max and Carcassonne I recommend them all but still advise playing the trial since they're not for everyone.
Both Assault Heroes games are best played co-op. My cousin and I got 200 GS on the first with practice. The second game is harder to 100%. If you don't care about achievements then it has some nice upgrades and you could go for that one over the first.
Rocket Riot is a lot of fun. The game gets difficult towards the end but it's very doable and challenging more than frustrating. I really enjoyed the online play where you can play football. Split up into teams and watch the chaos ensue. It's one of my favorite surprise games and I love the old school flavor.
Carcassonne is a great board game. You can play against bots or online. I like to play it when I want to relax and bought all the DLC with extra pieces, but it's not required at all and there are no achievements for them. Another easy 200 GS if that interests you.
Sam & Max is excellent. I love the offbeat humor and the second season was my first time playing an adventure game. I've been waiting for the first to go on sale so it's an insta-buy. I haven't played The Walking Dead games yet because I want to marathon them once all 5 episodes are out but I hear those are quite different than other TelltaleGames' games. Again, download the trial to see if it interests you. These adventure games take some different thinking to solve puzzles but are overall easy GS. Plus I'm sure there are guides if you get stuck
UPDATE: I checked the sale on the console and for LA Noire it says "Check back for tomorrow's 1-day deal". Someone linked to the Xbox Twitter account that said season passes were on sale. Maybe they'll do a new one each day.
I already have the Gears of War 3, Mortal Kombat and LA Noire passes and bought the Saints Row The Third DLC on sale. I'm hoping for the Max Payne 3 pass.
