You can softmod it easily on your own. However, make sure you don't pirate games, just make backups of the games you own, or it'll be illegal. You can play pretty much any game, as long as the software used to boot it has been patched for it (it might take a while for newer games to be supported, but older games usually are, especially if they're popular). You'll also be able to run homebrew, like emulators and stuff (make sure you own the game you're emulating, though).
Just look up how to softmod a Wii. Remember that the version you're using is very important. Also, make sure you follow all the instructions carefully, or you might be left with a bricked (unuseable) Wii. Hope this helped.
