Oh my god. What terrible spelling and grammar.
For beat em ups, the genre is near dead. You might have to look at some old games. Although the Wii does host some beat em ups. Here are list you might want to consider. The following like Godhand and Viewtiful Joe are on other consoles.
Viewtiful Joe, Godhand, Streets of Rage, Streets of Rage 2, Streets of Rage 3, Mad World, Final Fight(Nothing like the arcade version), Comix Zone.
As in shooters, what do you mean? There are different kinds of shooters. There are a lot of shooters on the virtual console and in Wiiware. As for other shooters, House of the Dead Overkill, Call of Duty: World at War, Castle of Shikigami 3, Resident Evil: Umbrella Chronicles and a bunch of other games.
As for RPGS. Again, thank that VC releases have been made. Considering the fact that the early 90s had some good RPGs. Anyways, as for modern RPGS, Rune Factory Frontier, Tales of Symphonia: Dawn of the New World, Final Fantasy: Chocobo's Dungeon, Final Fantasy Crystal Chronicles: Echoes of Time. For shits and giggles, you should get Secret of Mana.
