My main regret is that all that time and money (yes, i stupidly spent real money in his game) i invented is just gonna all go to waste.That's actually the main reason i didn't uninstall the game long ago.
Don't feel too bad. You paid to get extra enjoyment from the game. If you got that, then you're not really out anything. If you spent a bunch and never used what you got, or feel like it was substantially lamer than you thought, well then ... let's not speak of it.
