My Rules:
1. Buy 2 copies of each game new on release day. Has to be collector's edition.
1a. If it's on PS3 and 360, buy 2 copies on each console. If pre-order bonus included, bonus score. If not, no biggie.
1b. If no collector's edition, but has pre-order bonus, buy 2 copies for pre-order bonus. Bonus has to be in physical form. If not, no buy.
1c. If game has none of the above and only comes in regular version. No buy.
2. When physical game becomes cheap, buy.
2a. If game has a cheap digital version, buy digital version and keep physical version un-opened.
3. When finally not lazy, sell some goodies.
