Platinum Chip & The Legion

[Tonald]

How do I get out of the fort where Caesar is (while having the platinum chip) without doing his quest? Or if that's not possible, would doing the quest mess with me wanting to side with the NCR?

No, you can take the platinum chip, do the bunker quest and then leave and continue with the NCR missions.
You can also skip the whole thing. The NCR route is the only one where you do not have to deal with the chip at all.

The only way to leave the fort with the chip but without doing the bunker is to shoot/sneak your way out of there. You can meet the legionaries at the bunker, let them give you your stuff back then fight your way out, or go to the main gate and steal your stuff back from the lockers there.

But yeah, whatever you do in the bunker, it doesn't mess with the NCR route, what happens there is all about the House/Yes Man routes mostly.
