What can I say. I've never had any models in any game I've played in the last 30 years get "invalidated". Maybe I'm not "adventurous" enough to think outside the cubical polyhedron. Maybe it's because I just didn't like enough of the models from those factions. I'm also not a "one game or nothing" person. There's too many shinies out there to limit yourself to one game (and there'll always be new shinies). Why eat tofu at an all you can eat buffet? Sure, you may like tofu (why, I cannot fathom, but you do you. More bacon for me.) I get models because I like the look of those models, not because I identify with their faction, or I like the string of numbers that they use in a game. I play the faction that most of them fall into purely as a way to use them. Not for the joy of playing the game. I'm a builder, a maker, not a game player. For me, the game is a bonus to having those models, NOT the raison d'etre for owning them. To me, there are NO "invalidated" models. They just no longer have a function in this iteration. Every tool is a hammer at least once in its life, even if that wasn't its stated or intended use. It's cool to have something to use them in, but there ARE other rulesets out there that don't give a flying f*** at a rolling doughnut which models you use, and any "invalidated" models work fine with them (even *gasp* models from different manufacturers - getting together in poly-plastic and poly-metallic unions). As for the attachment to fluff. I'll take what I like from it and discard the rest - always have, always will. No matter the game OR genre piece. There's aspects of infinity's fluff I don't agree with and I just ignore those, just like the factions that revolve around them. Humans engaged in sufficient mutual co-operation to settle extra-solar planets - in less than a couple of centuries from now? You may as well tell me there are space wizards in the game.
