Guild Wars is officially supported, so it should be working very well soon: http://digital-conquest.ath.cx/wiki/index.php/Guild_Wars
Rome Total War however is unsupported, and it looks like you won't have much luck with it:
http://digital-conquest.ath.cx/wiki/index.php/Rome:_Total_War
It was last tested with 4.1 tho, so maybe works better in 4.4.1.
Make sure to check out the games database before investing in Cedega. Usually a minimum of four playability stars means it'll install and work very well.
