I just got into the series with 4u a little over a week ago, I played the Generations demo but I didn't like that jumping from anywhere seems OP. If I couldn't beat a monster using adept LS I just switched to aerial GS and won. I'll still probably buy it, though, but not until I've put in hundreds of hours into 4u to feel like I'm not wasting my money. So far, though, this has been one of the funnest games I've ever played, and I love the sense of reward I get after grinding for better equipment to take down a strong monster.
I've logged over three hundred hours into 3U, and I agree that generations isn't really appealing to me. All the new anime-esque abilities seem to just cater to the average populace, while also quickly breaking the game.
I main gunlance, but I can play hammer and bow too.
/shameless self promotion A friend and i are currently recording 3U for youtube, and we've just hit G rank, which is where the fun begins.
