Install and play... so you will feel how the original game is.
then Download HER 1.1 which was made for the Demo version only.
Install at the root of your MOHA game and say to overwrite all the files.
Then play it now with HER and take a look in the big difference.
Have fun!
ps: HER 1.1 doesn't have all the features of HER 2.3, but will give you a good idea about what HER will bring to the gameplay.
