I kinda regret buying ZanZarah: The Hidden Portal, a 3D fantasy adventure game where you fight, catch and collect fairies, train them and have them fight for you (yes, the game pretty much ripped of Pokémon. You even use balls or "spheres" to catch the fairies when they're low on health 
). I don't regret it because of the money spent (got it for like €1) but because I wasted so many precious hours on that mess (the game wasn't very good). But, on the bright side I did get a whole lot of new talking points to use next time I engage in a discussion about game design gone wrong.
Part of me actually regret that purchase because I did think the game had a lot of promise and it saddened me so much that the developers ended up messing it all up by injecting stupidity.
