Hi
all registration ideas here are good, but what if your 30 day trial version will
be cracked and extended to infinite-day trial :-))
Our application calculates unique id from pocketPC's hardware and
presents a user with his code. The user should send a code to us and we will
generate his key (it's generated by php online script).
In unregistered version gameplay is time-limited.
It all sounds nice, but one day some russian guy made a crack and
all you can do to fight a crack is to publish a new, feature-added version.....
So, any registration model is good, at least until cracked
