Great idea, great fix.
Grant anyone who buys $25 of Fallout Merchandise a slot in the beta, with $5 of that amount going towards their reserving a slot in the BETA and a chance to buy the game on opening day. Which by itself is another $50, $75 or $100.
$50 bare bones game
$75 game + map of game, and regular manual, maybe a bobble head or something
$100 game, map of game, walk through/compendium, bobble head, water chip, other 'toys' and whatever you want in a nice collectors box.
$150 package (full pre-order only) all of $100 game, plus art work, some items that only the $150 people can use (maybe a combat shotgun with 500 rounds of Faction ammo), maybe throw in a few copies of the original gamesas fallout games.
$10 a month, time cards available through game for ingame cash. Let OTHER players buy time cards and sell them in game for ingame cash. This way gamesas isn't on the hook for putting 'cards' in stores for a long time, other players act as banks for others that want game time but don't have cash and everyone wins.
Just make the time to grind up that sorta cash about 20 hours if the typical player plays 40 in a month. It lets players that have cash but no time have cash, and players that have cash but no time have time. Win win win
And best of all gamesas looks like a freaking hero for catering to so many players at once.
