A great follow up to the BN games, But if you don't like those, this one may not change your mind.
New to the game is the new battle grid, the game now has an over the shoulder perspective. Fight's now take place on a 6x3 grid. You can no longer move Forward or back, but only left and right. The way you fight has barley change as well. You still use battle chips to fight and the old megabuster, but the way there used is changed. Before when chips can only be selected in mutiple based on what letter was on the bottom of the chip, now if you select the same type of card, or if the cards are in the same columan. Also like the cards with the asterisk, you have cards that can go with any card. Also new is the Megabuster's charge system. Now it charges by it's slef, as oppse to when you had to hold down a button for it to charge.
And now holding down the buster's button you can rapid frie. Also new is a lock on system which let's you lock on to people in the same columan, or diagonal from you. By locking on to someone you can teleport infront of them before you use a battle chip. (Which makes using sword battle chips much easier to use.) Also they added a sheild that can be use to block attacks. These new addtion the battle system make the game fell a bit fresh, but don't make the game fell new. Also insted of "Jacking in" like you did in BN games, you go "On air" Which are preety much the same, expect that when you first go on air you are not in any devices yet, and you can still see the outside world, from here you can go in side a device.
Another new feature added is called "The brother band system where you can "Borrow" another players Favorite cards, best combos, and there giga cards. You can also get a brother force card. This new feature is cool, but isn't needed. Add the fact you need a fc to connect wifi and this really just seem like extra work.
The Starforce seris looks like a great follow up to BN. The mix of the new battle enginge lets people who played the other 6 BN games get a breath of fresh air, but other than that there is really nothing new in Star force.
You still have to run around and do quest for other people, slove decent puzzles, fight bosses who look hard at first but with the right plan can be taken down easily, and the same RPG elements. It has a "Been there done that" felling but still keeps the game from getting stale. And like I said before, If you didn't like BN there's most likely nothing new here to change your mind.
