Revenile: I'll say this, I did download the game to see what it was like, being very low on spendable funds for games, I gotta know that I'm going to like it. However two things occured after installing (the version I ended up with was from gamer's gate, as that version has a link to their site.)
I played for 10 minutes, just ten, then shut it off. I was so amazed with what the devs did to a game series that was originally a repainted Mario game due to Nintendo saying no to the devs who made the tech demo, so they changed the presentation and levels a bit and released it at the Giana Sisters, and now we have this game that really gives them an identity, and I had to buy it after my ten minutes of trying it out. The screen that popped up asking me to buy only made me want it more that the devs were awesome enough to basically say "we hope you enjoy the product and if you didn't buy it, consider doing so or donating." Very few devs would do that today, but yeah, I bought the game thanks to that screen and how great the game is, even waited for the sale to end to pay full price for it.
It was really kind of you, and as I said on my first message, it's a clever move on the devs. People that pirate games so they can "demo" them will get a remainder that, hey, the game isn't free. And if you enjoyed the game, you should pay for it, of course.
But after paying for it (Pirating it on the first place, or not), having the screen popping up once and again asking for it is just wrong.
BTW, I don't want to turn this thread into a "The game is still going to be pirated, so the screen needs to stay", or a "You want the screen removed because you pirated!" or something like that. I payed for the game. I don't want to be bothered anymore about paying for it. And I think I'm not being unreasonable on my demands...
