I could list all my favorite games here, but instead I will list games that you might not have played and I think that you should (some of these are in my favorite games list). I could give story synopsis' for these games but you could find them yourself.

• Ghost Trick: Phantom Detective -
Puzzle/mystery game made for the Nintendo DS, OST is amazing, story is amazing. It is told in such a way that things don't really make sense until the very end, but when it does it is incredibly satisfying. Even if you know the story it still has replay value, as its just that well told. Its made by the guy who made ace attorney, maybe a bit hard to find but its worth the hassle. If you are looking for a game to play it should be this one.

• VA-11 Hall-A: Cyberpunk Bartender Action -
Visual novel available here on steam, OST is phenomenal seriously (and is on spotify, always a plus), characters are lovely, story is great, had me tearing up at the end. The game maintains a very particular atmosphere which I loved, aided greatly by the amazing music. I recommend playing at night to keep with the atmosphere of the game, it enhanced my experience. The world-building done also kept me interested. Looking forward to the sequel.

Don't really know what to put for the game type, very strange game. Its a story focused on rails shooter, story is very out there but I thought it was very cool. OST is also very cool. Voice acting was well done too I noticed. Originally on the gamecube, it is now on steam. Still cant believe this was on the gamecube, its very unique.

• Hotel Dusk: Room 215 -
Visual Novel/Mystery game on the DS, music is very good (you might be noticing a pattern), gameplay is abnormal to other games like it on the DS, plus you hold the DS sideways which is interesting (made my arm sore though). The characters are drawn in a lovely rotoscoped art-style, which was a pleasure to look. The sequel has similar qualities, I reccomend them both.
