I just played Raw Data again, for the first time in version 0.2.
This game is just so great. My first time playing mission 3 (we play each mission twice in coop to unlock each upgrade), and it was a nice change of pace to play in a more open area. I also managed to "cheat" at the game by teleporting to an incined surface and then quickly moving another step in real live to reach a location which shouldn't be reachable. Fun stuff all around.
Overall, fighting in that game in coop is probably the most engaging moment-to-moment action game experience I've ever had, and by a good margin too.
Paintball in Rec Room is this for me. I find myself doing things I would typically do in real life (duck in tall grass, take cover behind obstacles, sneak up on people) more so than other multiplayer shooters in VR.
...I'm not sure why though.
