If gaming, or LFS, is someones hobby and they've money to invest in their hobby - then why ever not? I spend a small fortune on my own past times. LFS isn't really one of them at the moment but it has been a keen interest in the past.
The only down side is that a large TV screen usually finds its way to the lounge, and steering wheels don't attach to coffee tables terribly well.
But action films are jolly entertaining in 3D. Not all of them granted and 3D does suck for RomComs, but add LFS to the mix and the only objection anyone should have to buying one is whether there is the available cash, and whether you can clear the other half out of the lounge long enough to get the steering wheel out before her lack of soap operas drivers her crazy.
