I don't care if they are overused in indie games. Roguelike mechanics really do make a game more interesting such as actually punishing a player for dying and making each playthrough unique.
I plan on making roguelike mechanics an Ioncom staple.
I don't enjoy roguelikes but I accept that not every game is going to be made for me. Perhaps having stuff like permadeath as an option is a fair compromise depending on the game and feature. What do you thinkb?
