While a good first entry into this generation, Burst Limit falls a bit flat in some areas.
I'm a big 3D fighting game fan, and I've made a point to play all those I could on the 360 due to it being a small genre. Now, Burst Limit is a good game but it doesn't deliver itself as well as other games in the genre like your Dead or Alives, Virtua Fighters, and Soul Caliburs. I don't know if I'm just not used to the type of game this is, but while playing the fighting seems a bit clunky. Unlike other fighters, it just doesn't feel like you're delivering a fluid beating to your opponent. The separate combos are fluid enough, but while chaining them together it just feels like there is too much nothing in between attacks. This is obviously a very obscure complaint that only huge fans of the genre will find I believe. If you're more of a casual fighting game fan or just a DBZ fan, I doubt this will bother you.
A really good thing that Burst Limit does is emulate the source material really well. The whole look of the game is just fantastic. There is something about Akira Toriyama's character designs that just let them adapt to 3D so well. The cell shading does a great job at keeping the games look true to the manga and anime. It's a breath of fresh air to see a nice colorful game instead of the standard brown of this generation.
One thing that game doesn't do well emulating is the english voice acting. Alone it's just fine being they got the originals to voice the characters, but when switching between characters speaking, theres just too much time in between and the cut scenes just seem very awkwardly edited with the pauses. Luckily, the game also has the original japanese voice actors as well and it doesn't seem as awkward with the japanese turned on.
Another negative that I found was the general lack of characters. Sure you have the main characters from the Sayin, Freeza, and Cell saga, but compared to other games, the roster is just pitiful. Some of the characters available in Burst Limit are just pointless, Saibaimen? Why would I want to play as them? Why? There are only 21 characters (not counting Super Sayin, Freeza, or Cell transformations) which is pitiful compared to Budokai Tenkaichi 3 which had 161. Yes, Tankaiichi 3 spanned not only DBZ but Dragon Ball and Dragon Ball GT as well.
Another problem I have with the game is just that, it doesn't even span the complete DBZ story line. There is no Garlic Jr. (I would of let that one slide anyways) or Buu saga. Why they decided just to stop at Cell is beyond me. Yeah they need to save stuff for sequels, but Atari is doing so poorly they should of just delivered as much as they could. I find it stupid that I have to be stuck playing with Saibaimen when I could of been playing with characters like Gotenks and Super Sayin 3 if they simply would of included the Buu saga in the game.
Another big feature of the game is online, which if is going to be featured in a fighter IT NEEDS TO BE BALANCED. There is no question about that at all. And the sad thing is that it really isn't sometimes. There are spamable attacks that just come to commonly and can just ruin games. Yes in other games there are spamable attacks like Ryu Hayabusa's back flip / spear attack which most players did online in DoA4, but even then it is easily counterable leaving it balanced. Stuff like Vegeta's big bang attack one after another just ruins matches completely. Oh... and its laggy sometimes
Overall, it's a good game. I'm being generous due to it getting the look right and it's core mechanics being well executed. It is hard to recommend it for a buy even to the most hardcore of DBZ fans due to its lack of characters and over all stripped feeling.
