LoL maybe

but before I play only 5 games, I'd stop playing them overall or only play them like once a month, I'm reducing the time I'm playing them anyway right now.

I can only think of one game: DOTA 2. There're many games surely better than Dota but they cant keep me playing longer than 100 hours. I even lost interested in those game after finishing story mode.

Non steam game I can only think of is HOMM3 :)

Don't Starve. It is such a huge, uncontrolled world with a random world every new game, and there are oh, SO MANY frikkin' things to craft. Just when you think that you are done with science, it adds magic elements. The longer I play, the more I get to discover. Besides, it keeps getting updated with new content, new monsters, new stuff etcetera, so I find it hard I'll stop playing. In fact, I've been totally hooked on to it, and I am still not done. It offers so many things to do that it's hard to get off it.

TL;DR - Random worlds, new contents, lots of stuff to do.

Oh and Sims 3 I expect.

World of Warcraft - I don't actually play this currently as I am really tired of it but the updates and expansions would make this a good choice for long term play if you were limited to 5 games.

Banished - With the modkit coming, the sky's the limit when it comes to the sandbox possibilities of this game.

Euro Truck Simulator 2 - So relaxing and it took 50-60 hours for me to somewhat get tired of it, still think I'll go back to it. The most relaxing game I've ever played.

Grand Theft Auto V - Just so many things to do and even when you're bored you can go on and find something to do.

Hearthstone - Just for some casual fun, and so very well polished.
