Who Else all has played battletech?
What's Battletech?
Is it fun? Should I try it?
Will I end up spending a big chunk of my disposable income on books & manuals & little painted bits of pewter? 
Not fooling anyone, Cameron..but, assuming you are asking as trying to put it in the mouth of someone not
familiar with the game:
Battletech is a game focusing on giant robots blowing each other to bits, set in a universe of politics, backstabbing,
and interstellar powers. Yes, you can expect to spend some money on the core books(about 40-50 each, currently
4 books), or you can get them in pdf for about 15 a pop. Miniature are nice, but not needed. Only downside is that,
currently, map-packs are out of print...but we should be seeing their triumphant return this month or next month,
since the first map pack is slated for release this quarter.
