I also watched Titanic 3D and The Avengers 3D. 3D doesn't really translate into a photograph very well, but here are a couple of pictures anyway. I'll be the first to admit, 3D isn't my cup of tea, but it performed very well in producing a nice, crisp 3D image. You can read specifics about 3D, brightness, black level, skin tones, etc., in Art's review linked here.
The 3020e is very bright, and the built in speakers came in handy in the surround sound-less room I had to use to review it. The speakers are better than any of the other projectors with built in speakers I have reviewed, but don't expect 5.1 Dolby surround. They are adequate, and I would even go as far as calling them good, but not great. I had to keep it ghetto and use a blackout cloth to test this one, I figured it was better than projecting onto an off white wall. Most of us gamers aren't made of money, so the odds are we'd be playing on a wall, or on a DIY screen of some sort anyway. Even with the lack of a "proper screen", it still looked amazing.
This projector would work for me, because I normally game on a PC monitor, or on a TV in my bedroom. I typically use my projector for movies, television, and some Wii gaming when we have friends over. If you plan on doing all of your PC, and console gaming on a projector, then I would check out a DLP projector first. If your second priority is gaming, I would not hesitate in recommending the 3020e to you. The good definitely outweighs the bad when it comes to the 3020e, just not in the gaming department.
-EbenezerThe Good: Very bright Great color Great shadow detail Love the Epson remotes Decent built in speakers 3D (if it is something you care about) Wireless HDMI (a feature I did not have the opportunity to try, but Pete says it works great in his 5020e review) Great warranty (2 years) The Bad: Not very portable for gamers on the go Black level is good, but not great No lens shift Lacks CFI feature (not too big of a deal in my book) The Ugly: LAG LAG MAJOR LAG
