If you're not familiar with Second Life, it's a online "virtual world" that dates back to 2003, and though it is massively multiplayer, it does not have any objectives. It's more or less a 3D chat and roleplay client, but a group of users have done something incredible within it; they've made a Cyberpunk MMO called Remnants of Earth:
[Remnants of Earth has a] heavy basis around classic pen and paper RPGs elements, like; dice rolling, stats, monster fighting, story driven events, MMO-like adventuring, and gathering. RoE is the first second life pen and paper table top game in SL, while still keeping the core features of any other roleplay sim. Players can interact with NPCs and other players to accomplish goals, and even engage in heated PvP faction wars. We even have a full crafting and mining system! Think of RoE as a fully functioning table top game in SL, like Dungeons and Dragons, or ShadowRun.
Check out the trailer for it above.
