RA2 has many essential options for multiplayer, but as LKO said it's missing a lot of important stuff (for me the most important ones are no terrain deforming and the boring Dolphin sonic weapon which can't be done like the disruptor).
The engine is also a bit slower, the AI sucks compared to the TS AI engine and the Yuri's Revenge loading times are a nightmare (seriously, it takes 2-3 seconds to load Grand Canyon in TS, in YR it can take 2-3 minutes to load a four-player map

.. I wonder what did they do to mess up with the loading times so awfully (could probably be the copy protection LKO mentioned, not sure at all though.. since I haven't played YR for 2 years)).
