I gotta disagree with this one. I think everyone can at least appreciate the core gameplay, whether or not you played for 1 or 1000 hours.

The game is rewarding for its gameplay, not for the systems around it, unlike many games mentioned in this.

The only reason I kept playing Warframe was because every other game felt too slow. I'd been burnt out for months before I found Titanfall 2 and finally made the switch. Then hackers ruined TF|2 and now I don't really play anything these days.
