Rock Band 4 is a fantastic game with a lot of shortcomings that will (hopefully) be mitigated in future patches and paid DLC updates ala Street Fighter IV. As it stands now, the game is a rocking good time that is easy to recommend if you're in need of new plastic instruments and don't want to drag out you PS360 or Wii. Pros: All legacy DLC is compatible, with only certain tracks not available for download currently. Harmonix is actively trying to grant access to problematic DLC. The new guitar seems much better than the old RB strats, although I was more of a Guitar Hero controller user. New weekly DLC is confirmed and has happened, being announced every Monday now. Aerosmith and Van Halen are highlights of the first month of DLC. It's easier than ever to drop in and out of the game, freestyle solos are neat, and every single DLC track from 2007 to now has been given harmonies. Queen DLC has never been better. Harmonix has also released a legacy controller adapter that allows X360 instruments to work in the new game with no lag. PS3 legacy instruments only require their original dongles to work in RB4. Harmonix Twitter account (and the Rock Band account) are very active and constantly respond to feedback. Free December 8th patch is on the way to fix a few glaring flaws in the game and a Rock Band 3 export is also available in December for $15 - previous games will (likely) import for free at a later date. Instruments have the capability to be updated via micro USB (Xbone) or bluetooth (PS4). NOTE: you will require a laptop or desktop with either built in bluetooth or a dongle in order to update your instruments on PS4. From what I gather, the instruments will not update via Apple computers. Cons Some DLC is missing on the Xbox Marketplace - Smooth Criminal, Blackened, etc. Basically, delisted DLC is in a tough place due to first party restrictions, but Harmonix is trying to sort it out. The drums are terrible. Hardware wise, they feel like plastic drums of old; hardly shocking. However, in game is a different story entirely. I've constantly missed notes I feel I should hit, and rolls barely seem to work. I am not an expert player on drums, but a lot of dropped notes appear during my sessions. Madcatz and Harmonix are taking feedback from the community and are working on drums, with a couple of firmware updates already out. Character customization is almost nonexistent compared to even Rock Band 1. Seriously, the character creator is pitiful. Do not be shocked at how terribly lacking it is if you don't believe me. Dynamic fills on drums, in my opinion, are garbage. Stick with classic fills, as the new dynamic fills don' always match the music and are terrible when throwing you off beat. Freestyle solos can sound cool, but can completely destroy other songs. Come as you Are (Unplugged), for example, sounds like hot poo with freestyle solos on. Thankfully these can be turned on/off with a flick of the dpad. This is a big one for lots of folks, myself included: THERE IS NO PRACTICE MODE. That means there is no way to practice pitch or tone in demanding songs besides playing over and over again until you finally maybe hit it. There is no drum trainer either. Another biggie for a small subset of folks: THERE IS NO ION SUPPORT. I do not know if it is being worked on, I'm sorry. I'm not really a drummer. Oh, and if you were a Wii player, you will have no DLC. There is no Wii U version of RB4 planned, so all those purchases are tied to RB3 or whatever. Sorry if you invested a lot there. Worth it? In my opinion, the game is well worth its asking price. I've packed my X360 away and moved on to PC/PS4/XB1/Wii U, but Rock Band has always had a special place in my gaming heart. If you're a diehard fan with an urge to play on new systems, then this is for you. If you're a diehard RB3 player that still has their stuff out, I'd pass until a few more updates and see where RB4 stands. If you're a Wii player, I'd probably just give up and find a new game unless the lack of DLC doesn't bother you. Happy rocking!
