Well there are achievements/trophies that are just ridiculously tedious grinds, such trophies should have no place in any games.The good trophies are of the sort that have you doing challenging things that are perhaps a bit more difficult, but fun to do.
Uncharted: X number of kills with Y weapon is tedious. Hunting out all the treasures is fun.
Naruto Shippune UNH2: Fighting with all 40 characters 30 times is a stupid grind, which merely encourages the gamer to find a way to get through it in the shorte time possible, which has the effect of making a game less enjoyable, the opposite, I would have thought, of what trophies/achievements are meant for. Winning X number of online fights is fun.
