I did not see the video to know that it was a demo video, I only read what Torpid wrote; but this only reduces my ire, it does not extinguish it. I don't like exaggerated demo vids period. Thats just my opinion. If a company has to resort to such sensationalism to get attention then its a real turn off for me. Anarch is right, a number of companies use them but I made my point above. Wedge I never saw the vid with the executor either but I saw the screen shots; and it is feasible to put such a ship in with little health to show what happens when it is destroyed....but if they made the executor so powerful that it took out mon cals with the blast of a solitary turbo-laser or something as exaggerated then that would annoy me.
As for Valter it seems you missed my point. Unless it is implicitately stated it is not actual game play then one may expect to play something akin to what is shown when they buy the game. If they clearly state in the promo vid it is not real and exaggerated then fine, they can do what they like. A demo for me is a pre-full version release that can be played and plays exactly like the full game but with limited units/levels etc. Such 'promotional vids' shouldn't be called or referred to as demos in the strictest sense but it is a common term that is too easily attached to such a vid. If the only place PG showed this vid was at E3 and they were clear that it was only under development then that is fair enough. But its not uncommon for game companies to blur what is in demos and what is in full games over time, even if they release a demo, in which they can restrict access to the best stuff.
As for the game being in development; it is always in development; other wise we wouldnt need patches.
Wedge, the example i was thinking of related to the Alfa Romeo Brera that was a concept car and developed with a V8. I was hell bent on buying one but when it was released the biggest engine you could get was a 6. I was annoyed and I wont buy one now. Sure they will still sell but unless they put that V8 in will well never know how they could have sold. From the mags I read most enthusiasts wanted the V8. Fair enough the company wanted to change the car, that is entirely up to them, but i will spend my cash on something else.
