Hmm, with unmetered traffic? I played DarkGalaxy one month at home and we got a ~95€ bill, my dad wasn’t amused. Literally just DG’s website once a day.
I don't remember worrying about data usage. I got into wardriving and was torrenting from neighbors unsecured linksys ssids. Will never forget that warm feeling of hearing netstumbler pings picking up new APs.
