Tetris

There is a new Unreal Tournament in development and its free. It has an active player base. If you're looking to get back into UT, I'd recommend the newest one. Only drawbacks is there is only a few fully textured maps,

Rise of The Tomb Raider... its sort of like the old tomb raider games but with better graphics, a different Lara (personality), and they added crafting.

Child of Light - a fun but short single player rpg. Uses a party system & turned based fighting.

Arma 3 with the Apex and Marksman DLC. This game is hard due to its realism, complex controls, and steep learning curve. Its a military shooter / simulator. Probably not a game you're looking for but I think it's awesome.

lol, when you don't have the attention span for Skyrim

Can't imagine how much ritalin it would take for you to play a good game.

H1Z1

i played Skyrim too, and it sucked. In 2005 might've been interesting though

Ahhh, when your ritalin doesn't cover 'pretty.' I'm sorry for your lost.

My insurance doesn't cover skyrim

try WoW and Witcher 3

and STALKER

I think the 1st and the 3rd editions are the best. there are tons of mods for the 1st one(most suck but some are nice). The game has aged badly though
