ROMaster2

Despite having the same kind of quality as Mental Omega, the mod doesn't get nearly as much attention as one would expect. Maybe because it's a closed beta and information is scarce? I don't know, but I'm sure it'll pick up a LOT more steam once there's a public release.

If you're looking to play with each unit, this 'zoo' map will let you play with them immediately. I quickly threw it together with another map so it's not spectacularly made but it gets the job done. Right now it doesn't have naval or helipad air units but those wouldn't take long to find on your own. It also contains some story spoiler units so keep that in mind.

For players who play through the missions as fast as possible, I've added a leaderboard on speedrun.com for it: http://www.speedrun.com/mo -- It's the same site where the other C&C games' leaderboards are hosted. Until someone does a full campaign run, individual levels will be the default page.
 
If you submit a run it should be approved within 24 hours, though likely in less time than that.
 
Edit: If someone could tell me the different versions available, that'd be great so they can be noted.
 
Edit 2: To avoid flooding the thread I'll just mention updates by editing this post.
  
Rules have been defined fairly well. For full campaign runs:

• Real time beings on clicking "Play" for the first mission (offset -0.60 seconds)
• Real time ends when "Mission Accomplished" appears on screen in the final mission
• Game time is the sum of the times displayed at the end of each mission

And for individual missions:

• Real time begins on the first frame you gain control of the battlefield
• Real time ends on the frame "Mission Accomplished" appears on screen in the final mission
• Game time is the time displayed at the end of the mission
• Pausing is allowed (but discouraged)

Game time takes precident over real time. In the event of a tie, however, real time determines the winner.

Video recording is required for now so people can't claim fake records.

The timer offset is how long it takes to get to the first 'cutscene' like it is in vanilla RA2 and YR.

Load times are effectively a non-issue as game time is used.

For campaigns, there is an option to select which difficulty was ran when submitting. Once there's enough runs I'll make the difficulties act as separate categories again. It's not enabled now to prevent runs from being unnoticed because of the website's layout. It's a flip of a switch.

Currently there is only one version you can select from for submiting. I'll add 4.0 (or what they decide to call it) once it's released.

Individual mission submissions aren't required to record real time, it just for completion.

Now for something to consider: VMware snapshots

The snapshot function in VMware effectively allows you to make a save state of the operating system at any time. I've used it while practicing some missions, and while it is much slower than regular saves, it's incredibly handy. It's not better than vanilla's saving in anyway. With that said, should they be allowed for campaign runs? It's not giving much of an advantage, reloading a save is never faster even in vanilla, so optimal runs would never use it. It'd only be used by runners still trying to nail down the missions and would prefer not to lose loads of time from a mission restart. And as far as game time goes, that can be fixed by adding the time between the reloads. Oh, and this would only apply to campaigns, not ILs.
