The logo really isn't that bad, in fact I do like it. It's like a bragging rights, you get to tell anyone who plays your game you’re a proud user of Gamestudio. In the commercial version (I don't know about the others) you can still suppress the logo screen in development stage only with the -nwnd command. The logo screen is still there it just goes on then off practically, but once you compile your game or whatever your making the startup screen will be back to its original speed.
I also agree that the current screen isn't pretty at all.
It would be really cool if the engine developers added a feature where you can change it around with scripting.
