Spooky- I expect the usual 'newbie' flames for stating my opinions, especially when they go against the 'norm'.
No need to worry, doesnt really happen around here. . . Just post your questions in the right forum

. And my following reply is just that, only a reply.
Spooky- Considering this is little more that 'eye-candy' and adds absolutely nothing to the game.
Thats a little biased, as when you think about it, everything is done for that purpose, we have over 200 (300 now?) new units, fan-made that took their creators a considerable amount of time to make. By making these units, they didnt add anything drastic to the game, they didnt add an 'ignore terrain penalties' like PtW did, they are bringing 'nothing' new to the Civ community besides 'Eye-candy'. In fact, come to think of it, why does Civ iii have Animated leaderheads at all? Its certainly playable with a static one, or none at all, then why do they exist? Or, whats the point of the 'glossed over' backgrounds, that look like sandstone? I imagine it would be much easier for Firaxis to just make it look like a common windows file. The entire purpose of new units is mainly for eye-candy, and added depth for us history nuts. Now, if I was going to make a new unit, I would most likely choose to make it 'multi-figured', as I think it looks more real, and adds more of a egotistic feel to sending five or 10 units into enemy territory, to take over a empire. It adds more realism to the classic "Thats not a tank army! thats just a tank", when in reality, that tank is completely covering that mountain from view

. As for the game slowing down, Kryten already said the each Multi figured unit is only around 5kb bigger than its predecessor.
On the subject of walking backwards, then turning before running, I dont think its possible, as Kryten said:
Kryten- BTW, the 1st sequence uses 12 of the 15 death frames available, while the 2nd one uses all 15
