Yeah this game is a surefire banger cause of Arc Sys. However, the issue these days is that most fighting games only release some barebones roster and then they upcharge you to the moon for additional characters. Now this isn't as much of a big deal if you are less interested in the source material(in this case DFO, especially since I am one of those with no attachment). However, for those that love the source material it can be rough. Especially since they charge anywhere from $5-$7 per character.
An example of this for me was Dragon Ball FighterZ. Fortunately the characters that I preferred(mostly) ended up in the FighterZ pack that I bought at a later time(far after the game launched). However it is something like $104 I think for the ultimate pack. Though if you were to buy the characters individually or outside of the character passes then you would easily surpass this. Imagine being someone that bought SF5 at launch and then looking at the roster now.
