coxdr: X-com: UFO Defense - I never had the time to really learn this game though I want to. I am always super intimidated when I play it and have hardly got past the beginning of the game.
I have some suggestions, if I may:
1) You got money from different countries, at the end of the month. Some countries give you MORE money, so place your starting base in Europe (Germany) and the second base at the border between USA and Canada. Or the other way around.
2) The first base already have all it needs, for the moment. Every new base needs at least 1 Interceptor (a flying ship to shoot down UFOs), 1 Skyranger (a flying ship to transport troops so they can finish the aliens) and some troops (8 - 10 soldiers). In the second base you need to build the following: 2 Hangars (1 for Interceptor and 1 for Skyranger), a Living Quarters (for your troops), a General Store (for all the items) and a Radar (for detecting UFOs).
3) After the base modules are constructed you need to do the following things in that new base: hire the troops (8-10 soldiers), transfer 1 Interceptor from the first base to the second (or buy a new one), buy 1 Skyranger, and buy weapons and ammo for soldiers and for Interceptor. After the weapons arrive, equip your Interceptor and the troops.
4) In the first base you should do research (using scientist) and manufacture new items (using engineers). Research ASAP laser weapons and next plasma weapons, manufacture them and equip your soldiers. After that research armor for your soldiers and different airships and weapons for them.
5) Sell all things you don't need: weapons, ammo, allien bodies (keep 1 of each for study). Do not sell Elerium and Alien Alloys. Keep some UFO navigation and UFO power source.
6) Do NOT fight during night (unless you have no choice). UFOs crash site remain there for 1-2 days so plan your Skyranger to arrive there during daylight.
7) Be careful not to hire too many Scientists and Engineers, or their salary will bankrupt you.
8) Save often.
Follow these advices and you'll be fine.
