Yes. Creating tictactoe or chess in construct2 is possible. But one has to be very patient with tictactoe and very very patient in Chess. Before you do anything one has to understand the logic & moves and jot it down on a paper before starting. For a quicker way play Computer Chess / tictactoe taking all the moves while taking note on how the computer plays chess/ tictactoe. One for sure in every move you make the computer has been assigned what move it will make. Grab that information.
eg when you start playing tictactoe and put a cross on the first box maybe the computer has been assigned to play it its circle at the center and so on.
What I am doing in tictactoe looks promising but my fear is its going to surpass the 100 events limit. <img src="smileys/smiley24.gif" border="0" align="middle" /> For chess there is no doubt about it hence no need to start since I dont have the standard edition.
There is hope scirra guys.
Your limit is your imagination.
