I know, there's also the Steam option, my question was should I wait to try it when I have the money, or try it now to get a feel for it and then come back to it later hoping I don't forget everything?
You can create as many accounts and characters as you want so if you just wanna check it out for free, you shouldn't hesitate.
However, it's gonna take you more than 2 or 3 weeks to generate enough wealth to pay for your gametime. This is because skilling up your char to ordinary isk generating capacity takes a couple of months at least. 60 days costs you $35.
Through missions, on a sufficiently skilled character and a proper ship, you can earn a month of gametime in about 20 hours. This varies by skillpoints and ship. Actual ISK/h numbers of missioning are always disputed but the gist is there. 30 days of gametime costs 365 million isk. The ordinarily fit basic battleship you will be using to run missions for that isk costs about a third of that.
