I agree; if the console had been half the price it might have faired better.
Another issue is that pretty much every good game on there came out on other platforms, and often the other platform's version was actually better anyway. Return Fire, for example: great game, a lot of fun, but the PlayStation version is better in pretty much every way. Same with Road Rash, or The Horde (in a cheesy way, on the Saturn), Alone in the Dark (on the PC), etc. Despite being called the 3DO, it pretty much always had the absolute worst version of 3D games.
There are a few exclusives, and even a couple that are ok, but certainly not enough to justify the price tag. Even compared to the Saturn (a system that also tends to have pretty mediocre 3D experiences), it's pretty obvious that the 3DO is a bad deal.
