I only loved it for the mecha. Ral Partha was only just down the road from me so I could buy direct from the factory, I just had to wait for the right molds to be in casting. The story books were good and the Tech manuals too. It wasnt until the advent of the PC games and then later and better Mechwarrior 4 that the gaming side of it was at its best. The board game took hours to do and got a bit boring. the Xbox game while graphically good, game play was too kiddie-fied and just plain old sucks.
D and D may also be a bit on the dated side but as hoard of school kids take it up each year and only really requires a pen paper and a adventure book to play makes it sooo much easier. BattleTech needed so much more to make it worth the bother.
