Games like 2D Mario platformers I usually play for fun, no 100%, but sometimes I like to go out and get everything, like in Metroid or 3D Land/World.
Only first/third person shooter games I enjoy are TF2 and Splatoon, both usually are goofy and fun games but still rely on teamwork to win.
I have the ability to fly 10 inches in the air if spooked, so horror games are a big no-no.
I am a broke child so Smash is my only fighting game...
Games that have "the" fandom I tend to forget and never play, sorry DDLC and UT.
RPGS like Pokemon and the Mario & Luigi series I tend to grind at a reasonable level, but not until it becomes boring and dry.
Although I can't play most of them, I have a deep interest on those wacky no-sense games, such as Parodius and the Battle Cats, just because of how crazy they can be.
My favorite series is Kirby, because of:
The music,
The gameplay,
The surprisingly deep story,
The sudden nightmare fuel,
And the only God I worship, King Dedede.
Maro Party and Krat are my go-to group games, with the addition of Smash.
That's about it
Peace
