Just finished an online multiplayer adventure game called Kleeshae Caverns
www.hottestontv.com.au/loopWhere you go on quests, kill monsters, but also do some interaction etc.
It's based on the old LOGD 0.9.7t iteration but that was text-based, I've made mine picture/text and I can add sound, video or anything else.
Anyway, it's a lot of fun to create an expanding online world, I recommend worldbuilding to anyone!
