While there isn't enough here to keep you entertained, Reqaug is quick to stress that his work will "always be in progress." It's more a matter of investing enough time than whether or not a blocky Pokémon recreation is possible. And importantly, this doesn't require modding -- as long as you're using at least Minecraft 1.10, you can try it for yourself. Just don't expect an action game like one of the Super Mario Bros. titles, since Minecraft likely can't draw the virtual screen quickly enough to keep up.
