Just to repeat something I wrote in a different thread, I've come up with what I think is a pretty good rule of thumb of what separates 'good' or 'justifiable' microtransactions / DLC and what constitutes exploitative or extortive DLC.
1) Anything which has only a cosmetic effect on the game is acceptable and to be encouraged. Bonus costumes, decorations etc. (Although I do miss the days when such things were unlockable through gameplay achievements)
2) Anything which constitutes a permanent upgrade to the game is acceptable in single-player games *only*. In multi-player games this constitutes pay-to-win and is wrong - with the exception of upgrades that benefit all players equally, eg hosting services or exclusive maps available to paying customers.
3) Paid-for consumables are on the wrong side of the line. If I pay money for something, that should be a permanent upgrade, not something I use up quickly and go back to the bad old version.
Obviously it's only a rule of thumb and the dividing line isn't always obvious (eg - I pay to speed up a brick mine on Dungeon Keeper - this is a consumable but in a limited sense it also 'upgrades' my dungeon permanently). But I think it's still a pretty useful starting point for discussion.
