For fun, lets look at how much Injustice would REALLY cost if you wanted to buy EVERYTHING that is currently available(and more than likely will be available in the future) using the prices currently established at retail today as the template.
- The base product was 24 character for $60 at launch (collector's edition was $99)
- Lets say there will be 12 extra characters at $5 a piece - another $60 (which if you got the season passes you'd get $15 off - $45)
- Plus 12+ skin packages for all characters all at $3 a peice - $36
Total: $156
With Collector's Edition, new Total: $196
A F2P model where you could spend anywhere from $0 to $200 would be fine IMO, and of course if you wanted to get everyting it would get pricey, but the bottom line is that if you did that, THAT WOULD BE YOUR CHOICE...
and choice is always good.
Currently to get all the characters, just the characters, for Injustice you have to pay at least $80. unless you found a sale where you could save a lot of cash - $30 sale on base, $15 season pass - $45. If you are a tournament player who just wants all the characters you can still get off with a decent price (going by the Injustice model), it's only if you want EVERYTHING - skins, and other what nots - where you get into the really pricey area.
