VR would be really cool in HL2RP, it would disable the use of /me cause your pretty much doing the action already, the talking would have to be by voice and people playing female characters as males IRL would kind of screw the immersion up and 12 year olds in young adult bodies would also screw the immersion up as well.
In summery the idea is really cool but it wouldn't work out as intended since voice-chat can screw immersion up, if we had a voice to text thingy in VR that would be cool but there would be a lot of spelling mistakes.
