I agree with Handsup. The modding community for EM4 already has so many great mods that it's really not necessary or wanted to switch to EM5. Modders for EM4 are already familiar with its scripting, models, map editing, and everything in-between. The graphics for EM4 are perfectly fine by my standards especially for the style in which the game is meant to be played. EM5 has made an emphasis on graphical upgrades, which they did, but there are still a lot of issues with the game that have yet to be fixed. There's really no need, unless you're truly a graphics junky, to switch to EM5 when there are many modders/mod teams out there that have a lot of experience with EM4. In my opinion if the marvelous EM4 modders/mod teams do switch over to EM5 we'll have to wait as long as we did to get all the mods for EM4 we have today, but for EM5.
