>personally I tell myself that I love puzzle games, and I take pride in that because some of these games I get to finish lis TIS-100 are only completed by like 5% of the buyers according to steam.
Depends on how you qualify "finishing" the game. If you include the TIS-NET bonus campaign the dropoff is way worse.
I try to complete puzzle games (and any game) as best I can, but I'll confess I'm not always successful, and I couldn't really identify a pattern besides judging my own dedication against the game's difficulty. I 100%ed The Witness even though I didn't like it, and I haven't 100%ed The Talos Principle even though I really liked it. As far as Zach goes there are a few outstanding puzzles I've been saving for a rainy day, like the 63Corvi Mission and a few of the endgame puzzles for Shenzhen and Exapunks.
