Star Wars Galaxies guide... : General Discussion

Levels 1-5: You can either do the Newbie Tutorial on Tansarii Station and do quests there to level from 1-5, or if you skip the tutorial you will automatically be level 5.

Levels 5-10: These are really simple. Just do the quests you get from the beginning (the Legacy quests) and you'll be level 10 in no time.

Levels 10-50: Repeat levels 5-10. The Legacy quest is expansive, and goes to around level 50.

Level 50-60: Questing in Etyyy, the Hunting Grounds on Kashyyyk.

Level 60-70: Questing in the Rryatt (or whatever it's spelled) Trails on Kashyyyk.

Level 70-80: These are the tough levels. Get a group in Restuss, and have them escort you to do the antenna missions.

Level 80-90(finally): Do quests on Mustafar. There are a ton of them, and you get some great loot to use in PvP after you get 90.

Good luck on getting your level up! I hope I've helped.
