Introduction to SCW v4 I first started designing and creating the Spanish Civil War scenario for Civ2 MGE back in 2002 when I was just a teenager. Back then I reached José Pellón (a.k.a. @Kramsib) in the Spanish Apolyton Site for permission to use his wonderful Iberian Peninsula map. The first version (v1) of my MGE SCW scenario was first released in June 2003 and used the -back then- revolutionary "nemoesque" (@Captain Nemo 's) graphic style, @CurtSibling 's city improvement graphics, @Sarsstock 's Title image and the ability to play both challenging (thanks to events compensating the AI weakness) individual games against the computer and also exciting human vs human PBEM multiplayer games, which were quite popular back in the day in sites such as CFC (Civilization Fanatics Center), Apolyton.net, CDG (Creative Design Group) and the German Civ Webring site among others. The v1 scenario was beta-tested before public release by the Spanish Apolyton Site members jasev, @yaroslav, Amilca, El Léón, @academia, El Awrence, HsFB, belisariu and @Kramsib, the map designer. Several PBEM rounds and a full Demogame held at the -now gone- CDG site allowed me the release of an updated v2 version mid-year and a further v3 version was released in December 2003. That was the latest and "official" released version of the scenario. In 2008 Drew Shortis (a.k.a. @McMonkey) reached me asking for permission for a major ToT overhaul of my scenario. He did a great job and finally released "The Spanish Civil War ToTPP" in 2015, scenario which can be downloaded here and here. However, @McMonkey 's major rework of my scenario is only playable from the Republican side. Apart from this, I always wanted to implement some personal ideas I had in mind (airlifting African troops, aviation aces, buildable airplanes) and also fix some bugs that pre-existed in MGE SCW v3. It's been almost 20 years now since I first decided creating the SCW scenario but I have to admit I managed to start playing Civ2 ToT in my Windows 10 (now 11) machine, thanks to the efforts of several enthusiasts who keep this classic game alive and well, and I'm addicted. I'm currently rediscovering some classic scenarios which have been converted to ToT and use wonderfully designed graphics done by the most talented artists in the community. It's a new world compared to good old Civ2 MGE! Having said this, the time to redesign my "classic" scenario has come. It's now, thanks to the latest ToT and ToTPP with Lua capabilities which allow scenario making reach levels never imagined before, when I can put in practice all my ideas without the old MGE limitations. My starting point when I decided to upgrade v3 to a new v4 a few weeks ago consisted of: SCW v3 ToT conversion by @Catfish (http://users.tpg.com.au/jpwbeest/) done in 2009 and updated in 2010. Original SCW v3 ToT conversion by @Catfish 's files are available here. Latest set of ToT unit graphics created for this scenario by Gareth Birch (a.k.a. @Fairline) which are available here and here. Latest set of ToT 24bit terrain graphics created by @Catfish and @CurtSibling and compiled by @Fairline for multiple scenarios which are available here. This means the SCW v4 scenario development has started with having already a major graphic and Civ engine overhaul thanks to the work done by the above mentioned Civ2 enthusiasts. I can't thank you enough!
