You might want to look up what "The Elder Scrolls IV: Oblivion" actually is. And I _do_ have a Symbian version of it, sort of. It's called "Nethack" and it plays beautifully on a P910i.
But I'm still so going to buy Oblivion...
The real question should be "why do I have to spend a thousand bucks or so in hardware to be able to play a US$60 computer game?
