I believe the next one “Colony Wars” which releases in 2 days is worth it, as it is a full blown Set like the ones in Ascension, not like the Crisis: Expansions which are a glorified promo-deck if we want to draw comparisons again with Ascension.
To the worth of the mini-expansions:
Gambits: not liked much in a tournament setting, but aside from that the most value for money (most new cards included (gambits + all promo Cards Year 1)
Gambits are dealt at start randomly to players and can be used either one time only, while some have a lasting effect.
Spice things up really good, but can be a bit unfair to what gambits you are dealt. But against AI or non-tournament games they are great
Crisis: Several subsets sold and implemented seperately
Crisis: Fleets & Fortresses and Crisis: Bases & Battleships:
More of the same, no new mechanics
Crisis: Heroes
Something like “purchaseable gambits” Heroes can be purchased like bases and put directly in play and have a one-time use effect when scrapping them
Crisis: Events
Cards which are in the Purchase deck and have random effects which are dealt the moment they are unveiled by purchasing cards
Value/Fun:
if you only want to get One go for Gambits. if you want some more go for Events and Heroes next. I like B&b and F&F but they bring the least new stuff to the table. But I would over time get all of them. You can individually enable them much like in Ascension.
For example my longtime opponent/nemesis @kennfusion and I are playing concurrent games with everything enabled aside from gambits. Its fun I believe.

Speaking of which, now I knew why you didn’t challenge me again after our last match. I was puzzled by the missing rematch request, now I know whats up…
FINALLY COLONY WARS!
