I would like a free demo for the game, because I don't know whether I'd like it or not, and I don't want to spend money on a game that I would not play.
I meant to have a time limit, for example about 30 mins to an hour for play, so you can get the feel for the game.
I feel like in the days of so many YouTube user uploading hour long videos of very in-depth reviews and LP's a demo is not needed. Every game I have thought of buying and looked up a LP of it, my feel and final decision to buy it came from that. Definitely no to a demo from me.
