I would have to disagree - for some games Rps are good, they give a feel like you're playing at the arcade. Beat em ups are great on them. But the picture just doesn't cut it with the various racing games I've got, it's not crisp enough and you lose so much of the detail. I bought a 21" sony CRT for games - so my RP is for DVD and TV use only.
I've used a Tosh 40" RPTV with a PS2 and an X-BOX for over a year now, I've also got a 25" CRT TV and I'd rather use the RPTV for games any day. Picture quality is superb and, as long as you turn down the contrast, screen burn shouldn't be a problem.
