1) that\'s your lack of ram, yea ...the next version (Crystal Blue) should be easier on the resources :]
2) erm, in this version (Molecular Blue) you can basically explore the city, it\'s outskirts and dungeons, role play with other poeple and NPCs, collect crystals (diamonds are the rarest) ...oh, and there\'s a few quests :]
3) hehe, anywhere you want, but Kada\'s Tavern\'s a nice play to visit

...if i were as new as you, i\'d wait for someone more experienced to take me around the dungeons - you can get lost there pretty easily
4) you probably just came at a bad time ...on top of these forum pages there\'s a counter how many players are logged in the game right now - i hope that helps
and you can always ask a player anything in the game - most of us are very friendly ...but don\'t be discouraged if somone turns you down on your question - some have heard and answered some of the questions for n-thousand times already and/or just hada bad day ...the same players\' could later on prove very kind (trust me) :]
