yah, one hopes.
I have been playing SR2 a lot recently , which is much more than I ever played it after acquiring it about a year back on sale.
I have discovered in SR2 the 'bug' of them not following on stairs is not as bad as it often is in SR3. There are some occasions
and areas that have texture issues for whatever reason and they have problems following but not as mentioned so much on stairs.
So it is a bad habit that found its way into the code in SR3 I suppose. Since from what I understand the source code for the pc version
of SR2 is no where to be found, (so they mentioned the other day at that Twitch Volition SR playthru) I suppose they can not back track
where they screwed up on this.
ALso, since SRIV appears to be mostly a somewhat reworked SR3 it could well be the issue still exists. I guess we all get to find out in a few days.
( I say APPEARS simply because I base this off of plenty of pre-release footage gameplay, walks like a duck, quacks like a duck dead reckoning .)
I notice in SR2 though as is with SR3, IF the followers are having issues I can frequently just sort of baby walk them down or across something
when the issues occur. Not always but often. That is unless too much heat is on my tail in which case I flip them off and speed away.
