I do challenges for the fun of doing them, not for the reward.

Dark Souls at level 1 is absolutely worth doing if you’re replaying the game. It’s a lot of fun, and much easier than you’d think during your first time playthrough.

Surprisingly enough, playing Getting Over It 50 times over for the achievement is one of the most fun experiences I’ve ever had. The skill curve is just awesome to experience, my time dropped from 18h all the way down to 10 minutes.

Challenge not worth doing : all achievements on Rayman Legends. The game itself is amazing, but to get the last achievement you need to play daily procedural levels for MONTHS unless you’re a god at the game (and I’m pretty sure the top times are always cheated anyway, so you’re never getting the highest point reward anytime ever)
