The StarGate universe needs a "proper" video game series, definitely, I'd also be all over it. I am a StarGate SG-1 fan, I also really liked the first movie. I know some didn't like it but I thought it was good, and the main music theme is just awesome and so memorable and persisted to SG-1. I also liked SG Atlantis, I wouldn't say "as much as" SG-1 but still it was entertaining. I haven't seen a single SG Universe episode though, not sure how that one is doing. But, really, the direct-to-DVD SG-1 films were awesome, in my opinion, especially Ark of Truth, the whole Ori story arc was great (Continuum wasn't bad at all, but I just preferred Ark).
The only StarGate game I have ever played was on the SNES and it wasn't bad if memory serves me well. But, yeah, a good story-driven series set within that universe, or during SG-1 events, or whatever... just within that universe, would be nice. With this said however I don't think it would do well as an MMORPG, or MMOShooter or whatever MMO-stuff. It'd be very good if it was more in the veins of Mass Effect, story-driven, some exploration, some "hubs", have a crew SG-1 style and be in command of that crew, and go explore and quest (story-driven) in alien worlds from the SGC, take the StarGate to do so for each main missions, order your crew around during missions with some Rainbow Six-style grid-like planning on a top view of the area, find artifacts, etc.
Or maybe not, but something StarGate needs to be done yeah.
