I played Oarc with a Character on one of my four Servers right upto massive expansion and rocket launch, nuclear power, trains and Jet's. Spawning with a Character is a new features as of 4.2.21 - where a player can play as a Brave New Player (No Character) or spawn with a Character. This is due to comments that some players just can't deal with the game without hand crafting and having a character. It's definitely two very different ways of playing. I feel more free to come up with designs and work on blue prints in Non-Character mode. Hand crafting feels like I'm cheating when I play in that mode. The downside of hand crafting is that you can die, with a respawn in main, and you can't move as rapidly. But if you use Lexi-Aircrafts, you move pretty rapidly.
Another thing to know - If you spawn in Main-Force as a Character, then everyone who spawn in Main-Force will also need to be a Character, vice-versa is true - spawning as BNO Player will require everyone in Main-Force to be BNO Player. This is due to some settings that are required to get into BNO mode are Force Based. Give it a try - and if you prefer the OTHER mode, then just hit restart in the menu.
