So....I'm not really sure what this thread is trying to accomplish.
Generally speaking, the idea behind DLC is that if you like the game you've bought, DLC can extend that game's life and offer you cool stuff that you might like to use/play with in the game.
Extra expansion packs, characters, skins, etc.
Now, the industry has taken this idea and warped it into the monstrosity it is today, one look at Evolve's DLC practices is a good example.
Still, ultimately, the DLC is optional.
"But Rude!" You say, "If we want to be competitive, we HAVE to buy the DLC characters."
To steal a line from Infra Dead, "Nope."
If you're a competitive player, you can either find someone in your local scene who HAS the DLC characters and train against those people...
OR...
Find a training buddy online who plays those characters. Now, for those of you who believe that option isn't viable, I'd like to point out that Tyrant didn't even own a copy of MK9 personally and was one of the best Jax players in the world. The same could be said for Rico Suave, who also didn't own a copy of Injustice and was a consistent Top 8 placer early in the game's life. So let's just do away with that talking point, all right?
No one is putting a gun to your head and making you buy DLC. Don't want Jason? Don't buy him. Don't want extra skins? Don't buy them.
It sucks that Australian players have to pay more, but is that REALLY an NRS issue? Do you really think NRS has COMPLETE CONTROL over the pricing of their games?
I'm pretty sure local retailers have something to do with it, not to mention adjusted rates for different costs of living, inflation, so on and so forth. The point is, I'm very sure there is more than just NRS in play when talking about the price of a product.
Also, for those who find the price from a store to be too much to ask for, why not get the game after release, second hand? EBay, Amazon, even GameStop's official site. There is no reason to be married to brick and mortar stores. You could even get the game used a few months in at a lower price from EBay or something, and then ONLY buy the DLC that YOU want. Or none at all.
If you REALLY don't like this strategy by NRS? Do something about it. Boycott the game, start a petition, send an e-mail to a games' journalist like Yahtzee or Jim Sterling or Total Buscuit or any of those, and ask to them write about the topic. If the demand is high enough, they'll do it. Create awareness. Try.
Short version: Making threads on TYM won't fix the problem. Buy the DLC or don't, the choice is yours, but bitching about it doesn't solve anything.
