Quite simply, Aces High is everything Air Warrior could have been and more. I played Air Warrior right until the very end after starting in July 1998. I started playing Aces High as well as Air Warrior in April 2001 when many people made the move, including my squad.
A big difference for many former Air Warriors is the fact that Aces High is totally FR, and many of them were used to RR; however, most have adapted very well and are enjoying AH as much as they ever did AW - perhaps more.
Best advice I could give you is to download the game - and the help files - and practice offline as much as you can first. Read the Help files and have a look at places like
Netaces.org to get as much information as possible before venturing online. That way, you will be able to maximise your free two weeks to get the most from the game and made a decision. I do hope you decide to stay - there are lots of us former Air Warriors here, and you are bound to recognise lots of names.
Welcome to Aces High, and look forward to seeing you in the MA.
