Here are my suggestions (don't take these an insult, I mean no offense nor to criticize your abilities):
glerikud - Only made a couple small games but recently learned a lot about construct and need a project for next year so might as well start something. So mobile market is hopeless then. I spent long time trying to find good strategy game on google play but all were crap. Was hoping to find something like the old red alert quality, didn't find anything, so was thinking would it be possible put something of that quality on a phone. Targeting Strategy game audience who would search through them all like i did and if good pass it on.
I'd suggest you make a game in half a year if you can afford the time for it. It's purpose would be to learn how to design and make strategy games with C2. Also before you get into a big project that could take years to complete, it's better to have some mid-lenght projects done.
So what platforms can I build for with construct II? Cab I build for a desktop with construct II. I'm still a little confused with that. How to monetize with Construct II with Desktop if game is great?.
Go to Scirra's homepage and scroll down to the "Build Once. Publish Everywhere." section. There you can find all the platforms you can export with C2. Keep in mind that all exports (except the HTML5) use 3rd party wrappers to make your game run on those platforms.
Probably the best way to monetize a desktop game is to upload it to Steam Greenlight. Currently the Greenworks plugin for Construct 2 (which lets you use the Steamworks API) is broken, but a new version should be released soon. You can follow the news about it in this topic:
...I want players to be able play each other. Its not single player. Multiplayer.Ill have to get that peer to peer yoke Scirra have.I have a PC and laptop so testing will be a bit easier. Multiplayer should be easier than creating complex AI Single player mission
Before you even try to make a serious project using multiplayer, make some small multiplayer games if you did not already. Networking can be a mess and it's sometimes harder to code right than making a good AI.
