Finally! I'm tired of people complaining about lore not mattering because they're too lazy to read.
The older games are a good start to get you more interested, but they technically aren't official ("canon"). Reading the novels or even the technical readouts is helpful, but if you're like me, the cheapest way to do it would be to read articles on Sarna.net
"Sarna" is the online battletech wiki, almost ever mech, character, faction and event/war has a page(s). Plus seeing as you live in Norway, it might be hard to find the books, and even more expensive to ship them over to you.
Here is my favorite place to start off:
http://www.sarna.net/wiki/Timeline
The earlier stuff is mostly background, the "mechwarrior" as we know it is primarily between say, 3015 and 3070. This game takes place in 3049, so I'd weight your reading more into the 31st century side then work backwards as you want to see what caused things. There are a few interesting topics down into the 2400s but the newer stuff would be more relevant at first. Just keep clicking links, there is a massive amount of super detailed information on there.
