NURSERY

Normally, Ptaloid units can only be qued, and constructed one at a time like other moveable units.  If a nursery is placed next to a construction building, a player can optionally build up to 3 Protar, Galbonians, Pauks, Balkstones, Natulius, Pterdactyls and Infiltrators at the same time, like spawning Zerg units.  The only problem is, units cannot be qued.  For example, a player can build up to three Protar for a building, but cannot, for instance, que an additional Galbonian for that particular building.  That is why, even with a nursery attached, ordering multiple units built at once is optional.

What does qued means?

Also I love that building, it reminds me a Barrack add-on in SC that lets you build 2 marines at once, although you can't train Firebats, reapers nor other special units, then.

Qued means you have a unit ready to be produced.  A building can make only one unit at a time, but you can buy units early, and the building will make them as soon as it can.  For instance in SC, a Barracks can only build one marine at a time, but you can que up to 5 marines, firebats, etc.

In S.A.D. you can que up to 3 units.  Only one unit can be made at a time, but you can tell the building to make the next 2 as soon as it is able to.  Like I said, a nursery will allow a Ptaloid player to spawn units at once as if they were zerg larvae. 

Notice that I struck-out that last remark in my previous post, and what I mean is, like the zerg, you can have up to 3 DIFFERENT units produced at once.  I thought the S.A.D. engine would not allow that, but I was mistaken.

FORTRESS

The fortress produces Balkstones and Pterdactyls for the Ptaloid race.  Only Balkstones can be produced immediately, Pterdactyls require a Galactic Hermotha.

Looks really great!

just asking, but which one will be stronger: Splitron or Pterdactyls?

Splitrons are stronger, with Pterdactyls being proportionally cheaper.  However, Pterdatyls have the advantage of being ground-based vessels, meaning they can't be attacked by air-to-air units.

Nice. One thing I wonder is if it would be cool to generate some sort of creep or more web stuff around that building, which causes ground units that goes too close to move twice slower and air units to move twice slower while flying over the building?

Not a bad idea!  I'll have to think about that one.

Aah cool, I like how fast Zerg can be sometimes, it makes micro even more interesting. Glad you're considering speed upgrades for your game
