I agree, nothing but a gimmick...unless they do 4D! o0oo0o0o
Like the sega dreamcast smell-o-vision?
On the topic at hand, 3D gaming is a FAD! However, the three monitor set up is pretty cool. I thought I would hate bezels too but I got used to them very quickly especially since you don't look at the side screens dead on usually (they are like peripheral vision). However, I did not get used to the 3D gaming.
3D gaming is good for one thing: it limits how much you play. The glasses would just piss me off after 20 minutes. I never did get a headache; it was just really annoying to wear the bulky glasses. And if you looked away from the screen the glass spaz out for a bit plus the occasional microstutter equals lame gaming. Also, no one can watch you play (like if you are trading off) cause the screen is jacked. To top it all off, the 3d effect is "cool" but not great.
The 3 monitor set up, however, I ended up really liking. Originally, I thought I would just test it out, be like "oh ya this is kinda cool". Instead, I still use it, especially on FPS games. What I would love to do is set up 3 60 inch Mitsubishi DLP TVs (as low as $2400 for all three) using my 7.1 surround sound system. That would be incredible...
3D gaming won't be universal until glassless 3D monitors/tvs are available affordability.
Obviously, 3D surround gaming will not catch on. People have better uses to spend their money. Geez you have to have a minimum of 2 GTX 480s to do it! Plus 3 x $400 monitors, $200 glasses...too much except for the most diehard gamers.
