*whew* Awesome Series
Definetly an original idea of the whole series, I like it. I've seen all of the other episodes and hope to see the 8th episode soon enough. Granted, that various elements of the entire series could use some more work in terms of graphics, story scripts, and sounds, your work has almost inspired me to think about making a war campaign flash series based on SMB myself. So far, I've only downloaded 16 bit sprites and background sheets, but haven't made the move to actually start making a flash series. But if I did, I'd would want to make it because your work inspired me, and not because I was trying to be a copycat.
When it comes to custom sprites, I think most people don't appreciate the efforts that goes into spriting, especially customized sheets. Yes, it is true that sprite images offers some advantage over drawn ones that may appear to be easy way out, but actual work behind them.
In anycase, if I ever do decide to do a series like that, I'd know who to credit it for. (Feeling a bit of green envy that you came up with this idea first LOL :P )
