I never understood why anyone would make addons since it seems they are not 'allowed' to be used in missions/campaigns...
You always see missions being dubbed as '"Mission: Thunderbolt" - a completely addon free mission!!!'..
Same goes for campaigns...
Regular BIS units and Islands are sooooooooooooooo old, every single square nanometer has been used 876 593 782 837 689 times already...
Only thing bugging about that particular island is that all the addons needed in it needs to be downloaded separately, which is just dumb...
Of course using 56k is understandable reason in this case as downloading tons of addons would take days
However, there are winter islands made by
Instructor (I think they are smaller in size) the only drawback you might find is that they are strongly Finland influenced so that might not suite your needs...
All the islands do come in three different versions (no desert though)..
I probably would download this thing, all would depend on the storyline etc..
I just don't/wouldn't have the time to play it, that's all..
