We considered the arcade option as some of us play it over on PPForum. Personally I always feel like I am in the cellar when I'm in the arcade and the games are very limited so we have decided against it.
The arcade section here is a bit of fun really, something to do when it is quiet and the score board came after people had started posting screens. There is a very light and quick piece of screen-capture software called Quick Screen Capture v3.0.0 which is quite easy to find... and takes the chore out of taking screenshots of your score. You are also active in the thread so other people can see you're playing, and for me that makes it more interesting especially when you are the highscore holder.
If enough people wanted, it could be installed anytime and instantly so we'll keep it in mind.
Thanks for the input AKKDHOLI.
