Civ V is an option too! I love that game. But it gets boring for a while after a win. Starting over feels like a chore after you were nuking the enemy capitals to the ground and hearing their screams for mercy :3.

I need to get hungry for civ one again and that takes about a month or so.

Gta V is a wild one you have pretty much everything you want in a game pretty good pretty detailed fun guaranteed.

About the cs go part, you have to play it if you like the franchise!

Lots of things changed since 1.3 and you can play 5v5 official competitive in it. you should give a try.

That is a hard one! hmm.

i would probably go with CS:GO or GTA V

Since i am going to play it my whole life, it needs to be replayable. so waving goodbye to GTA. i would go with CS:GO
