I've been playing the crap outta Star Wars: The Old Republic recently. Definitely one of my new favorite games. I also still enjoy Minecraft, Portal 2, Garry's Mod, Super Smash Bros. Brawl, and The Long Dark.
-Every Halo game that i've played (Halo 1-4, Halo Wars, Halo Reach)
-Elder Scrolls: Oblivion and Skyrim.
-Fallout 3 and Fallout: New Vegas.
-Supreme Commander 2.
-Forza Horizon 2.
-Space Engineers (My main fave right now)
-Fortresscraft: Evolved (It's incomplete, but I see it going in a good direction.)
My favorite game in the world is Toy Commander. It's a classic title for the short-lived Dreamcast. I grew up with it. I used to play it day and night, and now I play it on the only emulator I've ever had.
Other wonderful games include Sonic Adventure/2, Paper Mario, Zelda and Pokemon.

3. Pokemon Mystery Dungeon - Explorers of sky, addicting-as-crack dungeon crawler with epic gameplay and music
4. Terraria, I don't think I need a description
5. Legend of Zelda Majora's Mask, I like how unique it is, and I love the masks
6. The Binding of Isaac: Rebirth, a game I suck at but can offer loads of fun
7. Animal Crossing: New Leaf, it's fun being a greedy aristocrat of a mayor making your town dope and watching your wealth grow until your favorite villagers move away and are replaced with ones that you hate that will NEVER MOVE OUT. Also, it's a prettied-up OCD discoverer.
8. Lego Marvel: Superheroes, it's a game I play when I just want to have some fun. Good grephicks and is all-around fun.
9. Megaman Battle Network 3/6, both are fun games although kind of obscure, but I enjoy them. Cool battle system and anybody that played the old NES Megamans might see some familiar faces.
10. Bravely Default, good JRPG and I love its job system. The combos you can do are cool, but it suffers from repetition at the end IMO.
Now that I made a list, it's time to remember a billion other games I should have included but didn't.
Roblox gameplay and community have gotten better a little bit, but the moderation team is still bad.
So many games here I haven't played, I feel like a scrub.
-Left 4 Dead (Both games)
-All Mario games except for Super Mario Bros. 2
-Rollercoaster Tycoon, first major game I played in my life. (5 years old)
-Every Call of Duty game Black Ops 2 and under (Except WaW)
-A really cool game called Airarret
-I enjoyed Gears of War a lot.
-Five Nights at Freddy's 1 and 2 were pretty fun, but anything after that was a flop.
-Binding of Isaac: Rebirth
I also enjoyed Minecraft at one point in my life, but then Microsoft came in...
