This real-time "strategy" game is way too short on strategy.
Galcon, by Galcon (amazingly enough), is billed as a real-time strategy game. Sadly, there just isn't enough real strategy here to warrant a glance from enthusiasts.
Galcon takes place through mini-battles, each of which occurs on an overhead map consisting of a variety of planets. Though there are a few modes to choose from, the main mode is the basic mode, in which you can see a number posted to each planet, which represents the number of units there. As soon as the game begins, you (and your AI opponent) begin selecting your own planets and then a new planet to take over, which sends 1/2 of the units from the original planet over to invade. Battles are virtually instant, and simple draw down numbers based the overall size of the platoon you've "organized". The goal being to wipe your opponent off the map, you'll need to think (albeit, very little) about how you're going about attacking planets, specifically since each one (including your enemies') has a specific number of troops. As time wears on (quickly) your planets regenerate population to send out at your whim.
The entire play takes place really quickly, and so being fast out of the gate and smart helps a bit. Ultimately, however, Galcon requires little strategy regardless of how you play. In just about any scenario, you can send all your troops immediately to take the opponents planets, and if you win you're virtually secured victory. Longer approaches (taking planets one after the other etc) work just fine too, but again the game really only involves sending your troops to low population planets, and then working your way up to higher ones, and occasinally taking everyone to unseat a big-population planet.
There are no upgrades, nothing other than taking one planet after the next. Despite a wide variety of difficulty levels, the first half of which are too easy and the second half of which are far too hard, the gameplay just isn't good enough to stand up to any sense of being a strategic game in any robust sense. It's features are far too simplistic, and the one-off games are far too short.
If you're looking for a strategy game for the iphone, i won't ward you away from Galcon, since i know some people enjoy the simplistic nature of the game, but it's ultimately not satisfying on any but a marginally simplistic level.
