i think you're making an awefully big assumption there.
i've seen microtransactions done poorly and i've seen them done well. instead of making blanket assumptions we should be judging the implementation game by game because DLC can be a great revenue generator when done well. i for one have probably spent as much on LBP addons as i did buying LBP and LBP2. i don't feel the amount of content on disc was at all gypped by the existence of DLC content.
You're right some DLC is very well done. I just like to assume the worst until a game proves otherwise.
Bet Shiken that COD would outsell Battlefield in 2018. http://gamrconnect.vgchartz.com/post.php?id=8749702
