Also, bare in mind that while it is nice to have them combined, the PAL software in particular is still sketchy, so games published by Sony and Nintendo and the other big publishers are more likely to have better up to date data. So while I am actually not suprised the top 10 publishers make up 3/4 of the sales (I thought it could be more tbh) It will be slightly skewed in their favour at the moment.
