Rage. Finishing the game from beginning to end. Disappointed. Then I replayed it and took a bit more of my time with it. Trying to appreciate what they've wanted to archieve and I love it.

So many...... like...

Virtue´s Last Reward,
Affordable Space Adventures,

Hyrule Warriors
etc. etc. etc. etc. etc.

It happens a lot with indie games.

Deadly Premonition. I remember checking some screens and thinking to myself "Geez, this game looks terrible". Went to the store the same day it released and for some reason it was 20 euros brand new, so I say why not and got it. Days later it became one of my favourite games ever, despite the rough edges.

Uhmmm... Can't really think of anything substantial, I usually have this feeling the other way around.

Folklore & The Reckoning, and quite a few indies.

Mario's Picross. I hate Puzzle games. I don't even know why I ever played that game.

Now I'm addicted.

Yeah. Unfortunately for me, I usually experience this phenomenon in reverse

Fallout 4, even after playing it i thought it was meh. Went back a few weeks later to give it a try again (Since I already paid the 60 for it, might as well give it another chance) and enjoyed it very much (2nd best game of last year behind Witcher 3)

Dark souls, very meh start, took over 20 hours, some google advice and a restart to get great. Sadly I don't have that kind of time anymore to persevere that long for games to get great. That would be almost 2 months with my current play time.

Telltale - Walking Dead
