Welcome to Smogon! Take a moment to read the Introduction to Smogon for a run-down on everything Smogon, and make sure you take some time to read the global rules.
I'm going to regret saying that, aren't I. I am looking forward to this new avatar you speak of. Is it in the style of the current one or is it a Cubone fusion? Rosebone sounds amazing.
I haven't played PSMD yet. :< But I typically play as Skitty in the older ones because Sing+Doubleslap is amazing. I finished PMD: Red in about 6 hours because of it. I imagine Bonemerang is similar though.
Bone Rush is similar, but long range and can even cover a curved line. Bonemerang will pierce through a straight line of enemies and hit them twice. Both are extremely strong as well. :D
The graphics are really great, actually. Characterwise, nothing will reach the team dynamic of explorers, but it's still quite fun so far. I'm not very far into the game yet, but I heard there will be an interesting plot twist somewhere along the way. ^^
The dungeons are harder from my experience, with much higher leveled foes. But Reviver Seeds are so abundant that you'll probably never find yourself failing a dungeon.
Hmm, I think I'll get a Gyarados now. I heard its giant Hydro Pump has a width of three tiles, and can crush through walls! And it can fly over cliff edges and even Mega evolve now. :D
