it is similar to R/B/Y in starters and stuff, but by the snapshots it looks like you also have access to the other regions, it looks like its capable of having all pokemon but i'm not sure, and zango is fine on my computer, it just adds another toolbar and i tried and can uninstall it with ease. It even gives instructions on how to uninstall it, graphics are the exact same as firered leafgreen except for some reason it won't give an attack command. But i think that's just because it's glitchy on my computer or in it's beta testing. It also has other actual people on at the time that you can battle.
