About 5000 $ on Ps3 (bought 3 ps3`s, first an older 60 GB model then when that stopped working I bought a Slim model for myself and one for my little sister, last time counted that was at least more then a ear ago was 50 + games, not all full price tho)
On the Wii I have not used very much, used about 250-300 $ (only have a few games, stopped playing after about half a year)
Since my country uses other currency I have compared to dollar (it is a bit more expensive in my country)
Now if takes the cost of pc gaming together with this then becomes very much (have at least 200 pc games bought this gen, mostly steam sales and have bought two computers within that time).
