We need a usable replay system.
I agree. It should be a option you can toggle for those with older PC's who don't want to hurt their framerate.
Yes I totally agree with you.
Definitely, it existed but poor implementation led it to be bad.
All OWI needed to do was not make the replay file viewable 2 hours after the file was created (2 hours being a safe estimate since it's the max length of a normal layer) and bam, meta gaming concerns are gone.
