I think a lot of people seem to misunderstand what EA is doing here with their microtransactions. Maybe I can summarize.
Dead Space 3 has implemented a new game mechanic. CRAFTING. You collect RESOURCES to build and purchase new weapon combinations. It's innovative. It's fun.
Collecting RESOURCES is a GRIND. Lot's of games have a GRIND. Final Fantasy VII had a GRIND for example. Many games give you something to do and a reward to work toward. Chasing a carrot on a stick can be fun.
EA has MONETIZED the GRIND in Dead Space 3. You can GRIND for RESOURCES if you want to, or you can pay $2.99 to get your resources RIGHT NOW. What does this mean? EA has created a FINANCIAL INCENTIVE for itself to make their games MORE FRUSTRATING. They have an INCENTIVE to make this game as FRUSTRATING as they can without ruining the game outright.
You can FARM for RESOURCES in some areas of the game. This isn't an EXPLOIT. It's not a CHEAT. You are repeating a monotonous task to get all the RESOURCES you want without having to pay for them. You are weighing the benefits of WASTING YOUR TIME or SPENDING YOUR MONEY. This is the foundation of this business model.
Many Free-To-Play games are monetized this way. The game is free, but you can unlock things faster if you pay. I personally hate games like that. They MONETIZE player FRUSTRATION. They create a PROBLEM and sell you the SOLUTION. Sell me whatever you want EA, but just don't do this. Anything but this.
Not all Free-To-Play are monetized this way. Dota 2 for example. All purchasable items are cosmetic. You can buy a cool hat, but you can't pay money to skip ahead to the good part. This is a much better microtransaction to live with. Perhaps there is hope for the future. I hope so.
Even if the game isn't horribly broken, I don't quite trust it anymore. Am I having fun right now, or am I just a chump running on some hamster wheel? Bringing money into it taints everything. This is why magazines keep their advertising and editorial departments in different parts of the building. Conflicts of interest start to arise.
EA will NICKEL-AND-DIME you for as much as you can TOLERATE. They are searching for the perfect sweet spot between
MAKING A GREAT GAME

EA is not EVIL. They are just EVIL ENOUGH... Which is actually a lot MORE EVIL when you think about it.
Dead Space 3 is pretty beautiful BTW
