No matter how long the grind is in the game (it's long), you can't help but be amazed at the scope of the thing, especially when you're NC and you're assaulting the purple guys at night. So, even if I'm a low level player with little certification points, I'm still having a blast and all of a sudden, boom a hundred cert points! That's the kind of grind that's fun, because you just play the game, have a blast, and you're rewarded.
DoTA 2 is also fun, because there is practically no grind at all. The game just makes you want to buy stuff by selling you stuff that's simply enhancing your experience without giving you any power!
War Thunder is okay-ish. It does feel a little more "grindy" (?), but you have to blame Wargaming for setting the trend of infinite, unpleasant grind.
and yeah, WoT sets the bar for worst grind ever
