i am a developer beginner with construct2.
You can see some of my works at matbo-spiele.de
as you can see graphics are not my thing :)
but I like creating and optimizing event sheets.
rpg and rts sound interesting. But with rts I always fear the performance with construct2. too much active, strong physic instances can slow down the fps very hard and too much means already 4 or 5 of them (my experiences). My favorites are turn-based games (like board-game-adaptions)
anyway, if you still need someone for the demos I provide my (hopefully increasing) skills and motivation! I look forward to analyse your concepts and to talk with you about them.
regards
