Should I purchase SH V?

At that price you will get alot from the game and yes, I agree, I admire steelviking for what he does and plans to do.
Hopefully himslf along with TDW, privateer, reaper7 and others will make a supermod once they figure out how to import ships into SH5.
At the moment it's the most dissappointing thing about it, the lack of variation in planes and ships.
