Here is the difference between platnum games and 90% of the industry today.
These guys make games that they want to make. They are not stuck making the same FPS every 2 years and being asked to milk one of their franchises until infinity. Thats why they left capcom...
Otherwise I played 3 of the 4 games and would rate their gameplay as follows.
Bayonetta - 10/10 (best game this year maybe this gen)
Madworld - 7.5/10
Vanquish - 8.5/10
As far as sales, Bayonetta sold really well for being a new IP. The fact that its pretty much critically acclaimed accross the board helps... Its sequel should do really well sales wise.
Madworld sold pretty good for what it is. A mature arcade style Wii game. It probably didn't cost much to make so they should be happy with those results.
Vanquish is stuck in the middle. Its a great game but it seems reviews arent as high and sales will flatten out around 500K for both consoles.
