15 Insanely Easy Xbox One Achievements You Must Unlock
7. Rare Replay - Various
The only reason this entry isn't at the top of the list is because it's going to include more than 20 achievements in one.
But those 20 achievements don't even require you to play a single game, technically. For the majority, all you need to do is load up a game and quit out the second the achievement pops for starting the game that first time. There are 20 of these achievements, which is going to net you well over 200G for simply just starting and quitting each game in quick succession.
On your way, you're going to earn a couple more achievements for "ranking up" and for collectively sampling each of a certain type of game, like all the Battletoads games for instance.
It's no surprise you can easily boost up your score this easily, considering Rare Replay is out of a grand total of 4000G. So is the inclusion of Rare Replay on this list cheating? Yeah, probably. But it's an extremely easy way to gain some Gamerscore very fast.
