the original thread below(free-play ww1) sounds cool... but
how about free play to early war main arena only?
i think early war provides a bigger motivation to convert to pay in order to access bigger, faster, stronger and much more lethal warbirds in mid and late war arenas.
also, i think non-subscribers should be bombarded with pop-up-ads everytime the player logs in and logs out
for example:
- catchy Flash-based video ad and/or "propaganda"-style pictoral ad encouraging new people and non-subs to pay

- ads for PC parts and joysticks...imagine HTC partnering with newegg for PC parts ad, HTC and Thrustmaster for joystick ad
