Don't Buy Versus Mode DLC
The size of the file's download is very small, meaning Capcom wants you to pay more for content that is already in the disk. This versus mode has no new content. No new content at all. It is just a Mercenaries mode that you can play online with other people. That's it. People are able to rage quit online to completely stop the game. After a while, it will start to bother you. And the simple fact that there is no disincentive for simply quitting and ruining everybody else's fun is more appalling.
