We are always interested in improving SuperCheats, so if you have any suggestions for the main site (not the forums please post them here.)
Here is some stuff that is in the pipeline.
1) Overhaul review system, to allow people to post full length reviews, with ratings for graphics, sound etc...
2) Overhaul walkthroughs system to show information such as version number and allow us and walkthrough authors to update them more easily.
If there is something specific you would like to see on SuperCheats, please post it here (Wish Lists, custom indexes with your favourite games, etc...).
