Finally received my copy of the Astro Port collection.
Had a quick go on the four games included:
First thoughts - Gigantic Army looks fun but might become a bit repetitive
Zangeri Warp - enjoyed this more than I was expecting - good fun warping
Satazius Next - graphics don't look that good via VGA - seems quite difficult but will give it a go
Wolflame - much harder than I was expecting.
Price does seem expensive but know sales are much smaller on dreamcast - packaging is nice as per usual.
