Pheace: You're missing out
OldFatGuy: Well, I've started three games (X-COM UFO Defense), and all three were on the easiest setting, and in all three I can't even get past the first battle. Now maybe I suck at games, but I don't think I suck THAT badly. Is this game intentionally incredibly hard? Or am I maybe missing something? I mean I'm not coming close to completing the very first mission on the easiest setting there is. Not. Even. Close. All of my men are dead before I've even gotten close to disabling more than one or two of theirs.
I don't get it. I've played tactical strategic games a million times and while I'm no expert I don't usually suck this badly. I can't figure it out.
It seems that you have to rethink your strategy completely, then. As in equipment, use of weapons and tools (light grenade for night battles: each member of the team should carry at least one; smoke grenades: they can make a great difference in survival), movement in the field, mutual support, management of time units, reserving time for reaction shots, kneeling, etcetera.
Think that just leaving the air vehicle is tactical already: you need to use smoke grenades, then step out (or be killed if you are unlucky: it may happen). Kneel some units with time for reaction shots so that they provide cover for the rest of the team. Use the cover that you can find, kneel, use light grenades when in the night... This is just for leaving the plane!
Think where is the alarm: it might happen that as you arrive the night falls and you will find yourself in a night battle without light grenades. Ouch.
Part of the fun is equipping your team for a mission. Another part of the fun was building your bases and distributing them around the world. The key for air combat is knowing when to quit before your plane is downed... And try to equip your fighters well so that they win.
The modern X-COM is way more gamey and very simplified, while the original games were simulations and demanded more from the player. Terror from the Deep was even more difficult. Apocalypse was different and very playable today.
If you find that it is too much, you might want to try X-Com: Apocalypse, which is a terrific game, and you can play it in real time with tactical pause and different speeds, if you want. It is tough as well but a different game, and there is no need for light grenades.
A couple thoughts more: the game is hard but very rewarding. You grow fond on your troopers. Getting some of them becoming colonels is really nice: they can help the rest of the team, but they need to be babysitted as well. Two is one, one is none, remember that. Never alone. Yet some of the most wonderful moments in this game come from surviving against overwhelming odds: See your team member infected and becoming a monster. Ouch. The rest of the team killing it, or becoming crazy and shooting anything in sight, or dropping their weapons (pistols add weight but might be a lifesaver). Scraping ammo from corpses in a protracted shooting. Facing an invasion from the enemy in a second-tier support base of yours with ill-trained troopers and obsolete rifles.
Troopers will die, it is up to you that they do not die in vain.
