Quoted from BriGuy5:
Still tough to stop people from cheating. Even if they have some kind of detection of the glass being on the machine, people could be crazy enough to cut a hole in the glass to cheat.
I'm not a serious enough player to actually care about if I get beat or not, and I despise cheating in anything I do, so I think it would be fun to play against some friends on here at random. I don't get anything out of cheating, so it would be fun to see how I fair against some other people I know on here but have never met. Sounds good to me!
In the grand scheme of things.... it doesn't matter much. Networked video games have the same problem and have had them since games went online. People will cheat, and that sucks, and it's a never-ending tug of war between anti-cheat detection and cheaters coming up with new ways to cheat. However, the overall benefit and fun of online play and the increased sales of the games overrides the drawbacks of cheaters. Also like video games, habitual cheaters will start to get a rep and people will simply avoid them or call them out on the forums.
