Well the game will be much slower than OP2 but still real time. Maybe take a week or two to research etc.
Ahh, that's what I was wondering about.
I at first thought it sounded a lot like Solar Realms Elite (or Barren Realms Elite, or Falcon's Eye, which were essentially the same game from the same maker, but with different text and storyline. Well, ok, a few other changes, but nothing too big). They had a similar building system, where you choose which buildings to build, and it would take so many turns/days to build it. Of course it only let you build one thing at a time, so it made sure the game lasted a while. Also, they gave you 12 turns a day, so you couldn't just play all day and get super powerful. I remember something about Barren Realms Elite allowing you to buy different types of terrain, like dessert, which would be good for solar power. Other terrain types might produce money or food.
Another game that's a little more real time was Trade Wars. It's some space based game where you can build up planets, start corporations with other players, and dominate the universe. You can build your own planets with genesis torpedos, but you needed to build a citadel on the planet to put defenses on it (which took days to build for each level). Defenses on a planet had much better attack/defense odds. The quasar connons you could build on planets were cool. They'd let you blast anyone entering the sector or trying to land on your planet. You could transport colonists from Earth to your planet, and they would produce stuff for you. Anyways, it was a great game. Absolute classic. It was probably the most popular BBS game ever made, and all these web based games seem to be the next evolution of this genre.
Oh, and the turn system in trade wars might be of use. They essentially allowed a certain number of turn per day, usualy depended on the universe size, and how quickly you wanted people to build up, and it was typically set around 300 to 1200 or so. Each action you did could take more than 1 turn though. So say you wanted to scan a nearby system to see what was going on, it would take 1 turn to do. If you wanted to move to an adjacent system in a small fast ship it might take 2 turns. If it was a big bad attack craft, it might take 6 or 12 turns. Originally, they just reset the turns everyday at midnight, but the more recent versions would restock 1/24 of your turns every hour. (The original versions were for BBS, so everyone was in the same city. It kinda made time zones a non issue). So, with the turn restocking every hour, you could either play what little you got every hour, or you could wait a whole day to play again when your turns had restocked to full. You couldn't stock up more turns than you'd get per day though. So if you didn't play for two days, some of the turns would be lost.
Maybe I'm just rambling, but hopefully some of those ideas are useful to you. They were certain some fun games though. (thumbsup)
