Warboy: Absolutely that was a joke, filler text. The point was that if you right click the energy bar you find out what it is, instead of wondering and needing to experiment. I thought it'd be more fun to read my idea if there were some funny parts.
As for young players, I was young when I started playing X-COM and Master Of Orion II. I learned MOO II with all the right click help, and X-COM we learned as a family. Keep in mind that we only had like 3 other games in the house.
It's easy to assume that it's the demand for strategy games like x-com that's dying without considering other aspects of the gaming market. Most games on today's market do a piss poor job of both designing and describing their new mechanics. There isn't a lack of a demand for complex strategy, there's a lack of investors.
Investors won't put money into strategy experiments because it's hit and miss, and bankers can't look at a game prototype and know whether it's good or not, especially for strategy. FPS, MMORPG and platformers will sell as long as the trailer is good, however 4x strategy will only sell well when the game mechanics are decent, something that can't be measured by investors before the game is complete.
Finally people who grew up without good strategy games aren't going to be aware of the possibility of good strategy games. X-COM is unique in that even now it still appeals to non-hardcore gamers immediately, it just looks interesting at first glance. Back in 04 when I was in the military I was in a processing unit that didn't allow us to leave the building for a day. They had a lounge with 12 computers, all of which had X-COM and everyone there was playing X-COM instead of Solitaire/Minesweeper.
Afterwards I talked to several people who wanted to know where to buy "that cool game in the lounge". Sadly I didn't have an answer at the time, I just knew it wasn't on the shelves anymore.
