In this case, I don't wanna use Firetuner. I prefer to win the achievements of me winning as a Civ, it just looks neat and makes me proud.
How could I forget this?: ... You can easily place resources (and other stuff) on the Map while inGame using
Cheat Map Editor from Zur13. The Mod can be enabled/disabled at any time, works even for already started Games. And it doesn't affect the Achievements (well, it's a cheat mod, so... ).
You select the CME Button in the Top right, select a tile on the Map, in the resource option select the resource you want (it has to be valid for that tile - but dw, it got a ToolTip that lists the valid tiles, otherwise you could also alter the terrain (but the art won't generate untill you restart the game)/feature of a tile too) and click apply.
You can also use Mods that alter resource placement, such as Got Lakes Map Script that
@Scrum Lord suggested (btw, a great Mod that adds replayability to the Maps (better exploration) ).
