Star Wars Battlefront HD is a collection of both main series Battlefront's. Featuring a new user interface to swap between the two games and their modes. It also features swapping modes in instant action, so you can play maps that appeared in Battlefront 1 with Battlefront 2 and vice versa without the use of mods (with the exception of space battles).
Including all the online modes of previous games, and the medal and scoring system from the second, if you reach a certain amount of points you will unlock maps from the spin off games Renegade Squadron and Elite Squadron, as well as the character creation and custom loadouts of said games.
Other features include auto-recognising controllers and splitscreen on the PC version, as well as other unlockables from The Clone Wars TV Series. The Ultimate Edition, exclusive to the Wii U, allows for the full versions of the PSP editions to be played on the Gamepad.
So I've explained the game and what I want from it, now the reasons I want it. For one, there is the compatibility issues on newer machines of PC, and the fact you cannot find a decent price for the original games on PS2 or Xbox any more, unless you are willing to pay the so called "Collector's Item" tax.
Another reason is that I use a controller, more specifically an Xbox 360 controller. It doesn't matter what controller you insert into your PC, you still have to manually configure the controls for about four different segments [soldier, vehicle, starfighter, turret, Jedi for BF2], and while this is only once, it still takes about a good ten minutes to get right.
