I don't play too many games from Steam although I have so much of them. Still prefer League of Legends or World of Warcraft. But if I play smth I like to do 100% in it (list at the bottom).
Also even if I buy new games I probably won't play it for a long time. I just like havin' them.

I love Bioware universes from Mass Effect to Dragon Age; and also more twisted narratives, like from McGee Alice. Besides I enjoy cleaning up question marks - something like in Witcher 3 or titles from the new era of Assasin's Creed.
In the meantime, it's also good to catch up on something more casuals things like old, classical J-RPGs or newer ones that fit in the same category - like Earthlock.

100% games that I didn't have - borrowed from friends libraries or just EA Play/etc:
They won't count until I buy them (I probably won't)
