Paying for air time isn't a barrier. If you guys knew how much I spend on banner ads each month you'd probably stuff yourselves.
The issue is creating the commercial itself. Even if I paid a marketing firm to make it for me, I'd still have to provide raw footage for them to use and a concept. It's not like they're going to become pro Blockland players and record themselves doing awesome stuff.Â
Hmmm, well I'm sure the Blockland community would be willing to help.
Although some aren't as creative as others >_>Another concern would be profit compare to cost, unless your not worried about that either.
As a raw concept though I think its a great idea.
