I haven't heard of VGA Planets, how does it play like?
Looks like they converted it over to a web based format as well:
Planets Nu. This seems to be a relatively faithful translation of VGAP.
Just a warning that I'm not so good with explaining games. That having been said:
It is a PBEM speed game (generally one turn a day or slower - several month games have always been normal). The main objects of control are planets, ships, and starbases.
There are a number of selectable race which are very obvious pulls from Star Trek, Star Wars, and Battlestar Galactica. Each one has various advantages and disadvantages. For example, one of the games I am in I am playing the Privateers, which have some ships that move at twice the normal speed, kill enemy crew at 3x the normal rate (ships are captured at 0 crew), and have a special "rob ship" mission that they can use to steal from enemy ships.
Planets are mineable for 4 different resources that have variable quantities and densities. Each planet has colonists that you place or native inhabitants. Each native inhabitant type and native government type gives different bonus (mining bonuses, easier taxation, or bonus tech levels at starbases built at that planet). Both population types grow based on the planet temperature and tax rate.
Below is my home planet on the left and the map as of turn 4 - I've colonized 3 planets (one on turn 2, two on turn 3). I have 4 ships, marked by the green circles and the lines mark the paths of the ships. I've highlighted one of my planets that has a native Amphibian race (Grants Tech Level 10 Beam Weapons to starbases around that planet).
Each Starbase takes a certain amount of resources to build and, as indicated, has it's own tech levels and uses the resources from the planet below to build ships.
Ships are built from base components (Each race has different, although overlapping, sets of hulls available. The beam weapons, engines, and torpedo types are standard.) . The slot type and count for each hull type are set. For example, below I am building a Lady Royale Class Cruiser. This always takes 2 engines, up to 4 Beam Weapons, and up to 1 torpedo launcher. Engine-Wise, I'm adding the top level, but otherwise, I'm going with mid to low-tier weaponry. This ship is being built not as a frontline fighter, but as a transport and credit generator (The Lady Royale Class has the special ability that if it is carrying clans (settlers), it will generate credits for each clan it is carrying).
The ships I've been building before this have been armed, cloakable transports that I can use to both spread colonies and capture any enemies I run into early if I don't think they are good candidates for an alliance.
Combat is very simple - one ship vs another ship at a time with no fine control. I haven't been in combat in the new game yet, but below is a shot from the combat visualizer from of of the battles of the last turn of the previous championship. Green triangles are fighters. The blue stars are torpedoes. Red lines are beam shots. Numbers next to the torpedo/fighter are the number available on that ship. These items generally need to be built at starbases, so it is possible to run out if you don't pay attention.
Below is a sample of the map of the final turn of the championship - the colored circles represent minefields (Except the yellow which are natural Ion storms).
And if you try out Planets Nu, you will notice that it does have a "Premier member" option that you can use. Otherwise, you are limited to tech 7 on starbases unless they are built around a planet with a native race that gives an automatic tech 10. As an interesting side note, this is exactly the same limitation that was present for unregistered players of the original Shareware game. Never posed a problem in the games I used to play (Since we either all played registered or all unregistered to keep an even playing field). Seems like it would be kind of pay-to-win with the online version, although it wouldn't make up for significant skill differences, especially for a Federation player.
