The price you pay for fan axxess is the total you pay for all DLC which is 10% cheaper than the individual costs totalled up. You won't need to pay for anything else.
The thing though, is that fan axxess isn't worth it if you aren't gonna buy(or use) 2 or 3 items from that DLC list.
10% might seem like a good deal, but when 10% equals like $2 or something...that's not really anything.
Look at it:
17 superstars(99 cents each),Accelerator($2,which I find to suck,since THQ KNOWS people edit attributes, they intentionally charged extra for that), Extra titles($2), Extra moves($2)
I believe Lesnars UFC attire is included in the extra moves DLC(along with his submission)?
Either way...that total comes to just about $23. So would you pay $20 for all of that, or pay individually for what you want? It's way better paying individually.
I see myself buying 10 superstars and MAYBE the attribute editor/extra moves(only if lesnars attire is included in it). So that total is still like $13 or something. Still much cheaper than paying $20 for the axxess pack.
Like I said, if there's at least 3 things you aren't gonna use from the DLC pack, then just buy stuff individually.
