Ooh, plastic is wonderful! The figures are cheap and you can chuck em across the kitchen floor without any worries! Plus I can chop em up and stick em together in all sorts of weird and wonderful postions.
If anyone noted a touch of sarcasm there, then you already know my opinion. Plastic figures are ok I guess, but they\'re not as detailed as metal (regardless of how good they are these days!). They are fun to stick together and you can interchange some parts (though I wish some people had better aesthetic judgement), but that doesn\'t necessarily make for a good set of figures.
Yeah, the costs of making moulds for plastics are prohibitively high for most companies. GW originally started experimenting with plastics around 1985/86 I think (Drastik Plastik Orcs & Psychostyrene Dwarves anyone?). The plastics they made in the late 80\'s were in addition to the metal models. You had a choice of good quality metal or the somewhat lesser quality plastics. Great if you wanted to build a large army quickly and didn\'t mind the compromise. However, these days GW don\'t give the option. I suppose it is more cost effective to just make either plastic or metal of a particular type of figure, but I reckon a lot of it has to do with the cost to the gamer. GW would never sell enough stuff if everything was metal these days as they\'ve outpriced the cost of their metal figures. Plastics are the only way people can afford to build armies (not that that\'s \'cheap\' these days either - plastic space marine devastators/jump troops being my point). For example, a box of space marines sets you back about £15 I think. If you wanted that squad in metal I think I\'m right in saying it\'d cost over £30!
I\'ll always remember reading the article in the Citadel Journal where Jervis Johnson (I think it was him) introduced the plastic figures back in the 80\'s. He said that plastics would not supercede metal. Hmm....
