Alright, got my first game sponsored. Here goes:
Arcade Cabin +++ & 1/2
Game sponsored was Pyrotec 2
After contacting several sponsors Arcade Cabin gave me the best offer of the bunch. After about a week of exchanging emails with Ralph, the owner, we got everything worked out, payment and all.
Seriousness +++
He knew what he wanted and wasn't afraid to ask for it, but never came off as strict or demanding. A fairly easy-going guy.
Money ++++
Good, but not spectacular. For the amount of work put into the game I couldn't really get much better than what he offered.
Efficiency ++++
This category is a bit of a problem for me since I'm currently going to school in Australia and the time difference made it hard for a hasty reply. Had I been back at home in the US, though, I'm certain his replies would have occurred in a more timely manner.
Social +++
Pretty much all talk was business, though he seemed like the kind of guy you could chat with about pretty much anything.
The biggest problem I had was with the amount of links he wanted in the game. If you'll notice I have a preloader, intro, and links plastered all over. That seems a bit much, which is why they get a 3 1/2 instead of 4.
Hope this helps.
