There's nothing wrong with having two listed for one franchise. There's no rule against it. However, I'm going to have to move either Doom 1 or Doom 2 into second spot and move everything else down one.
Ok, id remove Doom 2 from the list and Skyrim because the other 2 listed for those franchises are the ones that got me hooked. That 10th spot, you can just put Ghost Recon
