Hi TrekDude,
The graphics are beautiful, but just be aware that the current release can be slow & buggy for some people - remember to read all the FAQs and search before asking questions (especially if they\'re the kind that get asked a lot

)
In the current release you can run around, talk to other people and NPCs, pick up randomly spawning crystals, and try to get yourself into weird locations by taking advantage of glitches.
In the next release (soon, but no one knows exactly when) there will be basic fighting, magic, maybe crafting as well as more to explore.
Have a good time!
