re:My PC specs good enough for vanguard?
P4 2.8 Ghz
1gig of ram
Nvidia GeForce 5200 128MB
not sure what my motherboard is

The system is fine except for the video card -- I think that card doesn't support shader model 2.0, which Vanguard will require.

Re: What happens if you don't retrieve your corpse?
What we may do here and will likely toy with in beta is make it such that once your corpse is dragged you can no longer rez it. Simple rez timers may also be implemented if found to be necessary. Most certainly we do not want corpses to be used as a means of transportation as you described above and that has been exploited in other games.

Another big way to stop/hinder this would be to make it very costly to have a bunch of unrecovered corpses around the world. And there are many ways to do that, for the system to keep track of how many corpses you have out there, where they are, etc. Ultimately, I think there are plenty of ways/ideas to stop a situation where people die all over the place with one item on their corpse and the use rez as a means to one-time-per-corpse teleport to various areas.
