If you don't know what budget games are, they're the games that usually go for $20 new and they're really bad games that are rushed. One of the most notorious budget developers is
Data Design Interactive.
Developers of these games often rush the games by using the exact same game engine with multiple games and just swap the graphics and sound just so they can release as many as they can. Quantity over quality.
I've noticed that budget games appeared mostly on the PS2, Gamecube, GBA and DS. But once the PS3 and Xbox 360 came out, budget games only appeared on the Wii and DS probably due to that the budget developers can't afford PS3 and 360 dev kits.
With the Wii U coming out next year, and it being a powerful console like the PS3 and 360, I wonder if these crappy budget games will finally disappear along with the developers.
