[I'm goin' down]

I have a couple of comments.

First, TMO2.0, RSRDC, and OTC mod have been compatible for awhile, but TMO2.5 was not until the recent release of a complatible version of RSRDC and OTC, supra. As for the recent release, thanks CapnScurvy. Y Note, you can modify the above mod combination with Fred's pre December 7th start date mod.

Second, there was a dispute awhile back about whether the Americans knew Japanese ship lengths, as according RR, the Japanese tried to keep their ships' lengths a secret. If the ships' lengths were unknown to the American submariners, it undermines the realsim of the OTC mod for which input of ships' lengths is a key component. Personally, I do not care, as I like the OTC mod, and will continue to use it regardless.

Third, RR either stated or implied that optical targeting device that CapnScury created was not utilized, despite the fact that CapnScurvy has a picture of one. I think it is mentioned in the Submarine Firing Manual, too. I do not know what the truth is, and do not particularly care, as the OTC mod is one of my favorites. But some may have problems with the "authenticity" issue. I do not (not that what I think matters.)

Fourth, I prefer OTC to the 3D TDC and Radar Range Unit, because I always mix up the steps in the later mod. When that happens, I have to start my plan of attack over, and I either go nuts, screw up the attack, or both. Screwing up an attack with the 3D TDC mod means you have wasted an hour or two, and for me it translates into breaking my laptop out of frustration. For those with more patience, the 3D TDC is a great mod.

Fifth, another option is to use the Easy Aob mod in lieu of the OTC or 3D TDC and Radar Range Unit. It is much more "player" friendly, but is incompatible with both mods. The last time I tried it, the Easy Aob was not compatible with either of them. I have a fondness for the Easy Aob, because it was the first major technical break through of the recent generation of attack mods. Its creator, nicolas, is from south america, and is a computer programmer by trade. ddgrn then modified it for all of the Supermods, and readied it for downloading. He is from Canada. Two subsim superstars from yesteryear. But for pure creative genius, CapnScurvy and Nisgeis (3D TDC and Radar Range Unit) blew the doors off the vault. I will never forget watching Run Silent Run Deep, and jumping out of my chair when the camera scanned over a 3D TDC unit. I jumped up and said, "They copied Nisgeis' mod!" (But the sleazy producer left him out of the film credits!)

One final kudos for OTC. Its radar units, which you can install via a separate mod and use from the inception of the war if the boat is equipped with radar, is excellent. It picks up planes and ships, and makes playing with maps contacts disabled quite enjoyable. You can easily recognize aircraft, as they move accross the radar screen noticeably quickly in comparison to vessels. The tutorials re the various types of radar is an interesting and very informative read.
