Many of the suggestions for campaign play are very good.
I believe Alpha Strike has quite a bit of potential as a competitive game in a similar style to Warmachine, Flames of War, and some of the GW games. In order for that to be realized though, I think it desperately needs a few specific things:
1. Points values based upon Alpha Strike capabilities (this has been mentioned in many other replies here)
2. Standardized Missions based on 6'x4' tables and not map sheets (many of which are out of print anyway)
3. Force composition guidelines that are easy to follow and offer faction flavor
I REALLY like the suggestion of a reference indicating Common, Uncommon, Rare, Unavailable for each unit by faction and Era. It's simple.
I also like the suggestion of quirks and pilot abilities that can be used to modify units for a points cost. That allows sufficient customization to keep things interesting in pickup or tournament games.
I'd love nothing more than to see our local game store hosting tournaments a few times a year with a dozen players slugging out three rounds of mayhem for a small prize and bragging rights!
