About the post-KO counter.... bout time they did that. Honestly it bugged me that they always kept cutting it short in older games. Looking at the game it looks like it's trying to be more 'gritty' with the whole showing injuries and blood and "toning down the sexiness" as they say (though, considering this is freaking DOA, I SERIOUSLY wonder how long they're gonna hold onto that after DOA5 tried the same exact thing...). I'm still planning on getting it, but I really don't like how some other fans are going overboard about the whole 'the game got censored!!! Blame the SJWs!" nonsense again. Seriously, the game's still gonna have beautiful girls in it; just perhaps not as utterly ludicrous with stuff like "OMG" breast mode (I admit I use it too currently in DOA5, but I'm not the type to throw a fit if it goes away or anything.)
I personally don't have a worry about the roster, as it's extremely rare anyone gets dropped from a DOA game. All I want is more legacy/past outfits and... let's be real, a less-expensive DLC model. DOA5 literally set the record for most expensive post-content; they should try to be a LITTLE bit more reserved this next time around.
