Few months ago i started writing storyline of game I want to make (some tactical rpg/strategy a bit similar to xcom series). The thing is that i know programing (i work as ABAP developer for over 6 years, also having some knowledge of C#, VB and pascal programming), so i know how to make a logic of a game, but graphics, textures etc, are quite a different story (last time i did something with graphic in my coding was 2d platform game in pascal language like 10 years ago).
So I wanted to ask You guys, how you solve this? Where do You get animations, textures etc? Are there some freeware databases or You cooperate with some other ppl that can do graphics? How this can be arranged etc. Also is it better at beginning of making games to use some freeware game engines (if so, does anyone know some nice isometric game engine?), or to write it from beginning?
