Daddog,
The use of GVs would be an interesting feature for a TOD but may I point out a couple of things that would concern me with using them in a 1 life event:
1) Ease of death: GVs die to a light brush with a sheep or shrub...
2) Ease of death: GVs can't maneuver quickly to avoid attack by fighters or other GVs...
3) Ease of death: GVs die/get disabled easily by cannon and mg fire from strafing planes...
hmmmm... I think my concerns are clear...
Anyway, I'll make sure Midnight states our side preference soon.
