Just like Shawn, it was originally the model kits that drew me into Macross (even though I'm not really a model builder).
Back in 1982 or 1983, I was living in UK and the Imai and Arii Macross models were being imported into UK and fairly widely available in most model shops (at least in the area I lived). As soon as I saw the box art, I was blown away by the designs and had to start buying as many of these kits as possible (not easy when my pocket money was something like 50p a week).
From the time I'd spent in HK during 1976 to 1979, I realised that these models must be from a Japanese cartoon (I hadn't even heard of the term 'anime' back then) and I so loved the designs, that as corny as it sounds, I promised myself that one day I would find a way to watch the cartoon that these lovely model kits were from.
Fast forward to 1986, I'm back in Hong Kong and manage to catch an episode on Macross on TV, which starts to renew my interest in the show. However, it was not until 1987 when I saw DYRL on Laser Disc that I really got into Macross and began my obsession with the show and especially the toys.
It's now 2004 and Macross is one of the main loves of my life. Macross and it's sequels are my all time favorite animes and I've spent an insane amount of money over the past 17 years, tracking down and buying Macross toys, CDs, books, games and other miscellaneous Macross junk
Although I love all aspects of Macross, it's probably the mechanical designs and mecha combat that attract me the most.
