You obviously forgot the option to purchase credits for real money, in order to purchase crates.
Granted, that isn’t what I would call an ‘upfront’ cost, and I highly doubt anyone would be willing to stump up a large amount of money just for mercs (unless it was part of a bonus package).
But if you look at what someone that actually enjoys the game might be willing to pay, to unlock all mercs (when they become available) and then to attempt to purchase loadout cards, you are looking at somewhere in that region.
I used dollars as a rough example anyway, I am British, so I would be thinking in terms of pounds. I have no idea how many more mercs are to come, but looking at the wiki, there are 19 mercs in total.
So lets take the given, that Skyhammer and Aura are free, that leaves 17, then lets assume that the average player uses his free credit giveaways to purchase one of the cheaper mercs. That leaves 16 mercs.
From the 8 available, 2 of them are free, and 2 of them are high price. That leaves 3 of them for the price of £4.79 (you got one free remember), and 2 more for £6.99. That comes to £28.35, just for the mercs we have available right now today (and not counting the one you get for the ‘free’ credit charity).
That leaves 11 potential mercs, and let’s be conservative here, and assume Nexon wont raise the price, and will stay will £6.99 for the rest of them. That would be £76.89 for the remaining, unreleased mercs, assuming they all cost the same as Fragger.
So here we go, simple addition, £76.89 + £28.35 = £105.24. And using the current exchange rate, that is $153.98.
Granted, there are many assumptions there, and in actual fact, I just made a rough guess when I chose that previous number, and it wasn’t far off.
So tell me, is my maths wrong? Is my digital information wrong? Are my assumptions too wild or inaccurate?
