I've seen much worse domains registered by new members.
activehacks - First thing that came into my head was obviously hacking and the more underground side of things. Although 'hacks' can mean a variety of things online. I'd be tempted to say low - mid $xx 'resale' value.
aggressivegamers - How many times do you think this is spelt wrong in a day? It sounds good, but it is a fairly long domain. Easier to say than type. Could make a nice niche site though. Probably lower end of $xx, resale.
Just my opinions - good luck! And incase you wasnt sure the difference between resale and end-user...
End-user would be an individual contacting you and wanting your domain with intention to develop, generally.
Resale - such as a member here buying the domain with the intention of making money reselling it.
The 'resale' valuation will always be lower than 'end-user' appraisals.
