I think you should keep the current format but expand it more... You could add:
1) The ability to choose 10 of 25 games you predict on but give a multiplier on each one based on how likely it is to be right like in sports betting... For example, a game that has been out for 3 months and is consistently the same sales could be a 1.1 multiplier, but a new game this week could be a 3.0 multiplier...
2) The ability to research more via the site would be nice... Things like a query to get the opening 6 weeks sales of games in some sort of table or graph for a given platform, or classify games as AAA, AA, A, and B and then be able to get the opening weeks sales for a given platform. Or tie games of sequels together and query what each version did over a time frame.
3) There should be consistency on the days that the predictions league input will be available so people know when to look rather then constantly visiting just to see if this week's is ready or not.
4) The altime scores should be there but the last year or half year should also be there. I find the last 10 weeks to be too short term, and the alltime to be too long term, there should be a middle term of 1 year or 6 months seems good to me.
5) Hardware bundled software should be exluded from predictions... WiiPlay will always be some portion of Wii sales, from 40-65% (sometimes out a bit but it tends to be consistent) so WiiPlay shouldn't be there because if it is right chances are your Wii hardware is right, and if it is wrong the same is true.
I like the current format as it is simple and based on how well you can predict period. You don't make decisions based on anything other than raw predictions. When you go to a wealth system, people manage their wealth more and it requires more time and effort to excel at it. Hedging, selling short, etc. would all be involved in a new one and to tell you the truth simExchange has it pretty down so you would be competing with them. The current format could be expanded and added to so that you are more different then them.
