Probably Airport, its very popular for some reason...I find it boring lol http://www.vietcong-coop.net/site?node_id=6&action=show_data&cls_fileclass=null&ordercol=nf_accesscount&ordertype=desc&row=1&p_id=177
Do you mean biggest by filesize, biggest by area or biggest by number of players?
If you mean number of players, Airport is for 16 players, so very "big"
If you mean by area, also Airport is very big. Maybe you can also try SqBaker-OpSake4 (part 4, not version), it was part of one special mission and it is also very big
If you mean biggest by filesize, it can be TR-CityAttack with 117MB, next are [MCF]FrenchCampBeta1 with 87MB, OrangeCity 83MB, [AT]DayBreak 66MB, NioGianh1.2 60MB, EaglesCanyon_I (and all similar versions) about 59MB...
Yeah, I meant the biggest area to explore... OK so Airport is quite large according to you guys. Do you know what is the size of the map? Is it like 5km x 5km or larger?
What could be theoretically the biggest map supported by Ptero-Engine II? Is it possible to construct Arma size maps?
Hehe, no, it is not so big :-) Ofcourse there are limitations but I think nobody tried how big map can be made. Problem is number of objects and waypoints. Forget Arma size maps.
I'm going to answer my own question here. I found some time to work more with the editor. Using ruler it seems Ptero-Engine II works on a grid based on units 1m x 1m -- so the nearest targets are at 30m, then 50m and then 100m.
It would be nice to have a shooting range map with targets far beyond 100m.
