So if you've already heard of this or already downloaded it, you know exactly what I'm talking about and why I'm gettin' 8-bit high.

The game is pretty much Grand Theft Auto only NES-erized and loaded with 80s and 90s video game references and pop culture. It parodies classic titles, as well as obscure ones and pokes fun at the retro ages. For example: Metal Gear's localization to the US on NES and how the text wasn't properly translated is referenced here, and it's friggin' hilarious.
It even features pop culture like Super Meat Boy, Epic Meal Time, Trailer Park Boys, and sooo much more.
If you got 10 bucks to spare and feel like having some retro good time, I suggest this lil' download title.
