This could possibly create redundant-looking rankings (not to mention data):
Best video games of all time:
- Skyrim (PC)
- Skyrim (PlayStation)
- Skyrim (Xbox)
- Fallout 4 (PC)
- Fallout 4 (PlayStation)
- Fallout 4 (Xbox), etc.
Tetris: 8 as PC game, 6 as PS game, 4 as Xbox game
The group best ranking (video games in our example) takes the best rating only. So, in the video games ranking Tetris would go with 8. It would also be possible to use the group average ranking (that would've given Tetris a 6), but I think taking the best rating is a better idea.
Having said that, I'm not sure about this idea in general. I'll give it a thought and cast my vote later.
Now, games that are remastered/enhanced/etc. should definitely be added as separate items. If they're named the same, the remastered edition should have an additional info set (e.g. (remastered edition)). Not as the name info, but as a part of the title.
Update: After giving this structure a consideration, I think the idea is good. It seems that we all agree, and as X said, there's nothing to wait for. Some changes will be required, but they shouldn't be drastic. I also need to write a new function that will help us to handle the changes. When it's done, I'll let you know via PM and we'll start.
