I think it should have it's own page, but I want to make sure so I'm asking you.
Same Game Just On PC, so no
Far Cry 3 has better graphics and level editor, should that have its own page?? Just a Example
If Far Cry 3 had both the previous games included then you'd have a comparison.
Then you'd have a compilation, which don't get pages. I don't think Trials Evolution Gold should have a different page.
