I have enough exp to get a combat, light, and heavy weapons license, but I don't have enough money to purchase all 3. To purchase all 3 costs 6000 credits. I only have 3300 credits. Each license costs 2000 credits, so I have enough to buy 1 license, but it won't let me buy just one. I would like the ability to pick and choose which license(s) I want to purchase rather than being forced to purchase all at once.

It's not a flaw, per se, but it would be a nice improvement.

Yes, it was supposed to work this way (individual license purchases). I believe this is on The List.

I agree that people should be able play the game as they wish. It seems that Vendetta is all about freedom.
You should know that credits are very easy to come by. I've never come back from leveling without the credits for the license. or two or three.
Pick up those sparkling cargo crates.

IT would be nice to buy individual licenses. I purchased 3 at a time and accidentally spent all my money. My fault though, I should have read the cost better...

Yup, it sucks you can't do that. To get the cash in the meantime, do a quick trade run. It's best to buy an expensive item, as you'll make more profit off them. Buy something that's not available at the station you're going to.

I was in exactly the same situation as you. I had 4,000 credits and needed 9000. I bought luxury items and took them to a mining station and ended up with 36,000. More then enough for my licences AND to buy a new ship/weapons.
