That's not true, the Lumia 610, 620, 810 and 820 are WP8 also.
The cheapest one is the 610/620, you can get one unlocked from 300$ from expansys.ca. The 810/820 is a little more expensive, around 560-580$. And the Lumia 920 ~780$. Ouch
Exactly what I was thinking. Games seem to be either Nokia exclusive or making the jump to WP8. And as others have more eloquently put it, there's compatability issues up the ass, not to mention what seems like only two WP8 phones on the market in the Lumia 900 and 920.
