As the name states I would think that a small island addon say 1km x 1km in size with loads of detail, ditches, streams, hills, houses. I suggest as I have recently read a few war books and the authors regulary talk about holding a particular ditch, or fighting for control of a small but tactically significant hill. Currently the OFP maps are large with not alot of detail but a small detailed island addon would make for some good missions. Thanks for reading.
