So far didn't regret buy/play this game. Heard a lot of negative comment / low mark for this game but if you are really type of tactical / strategy game which some time require a lot of thinking before you executed it, this game is recommend for you
Also i realize although you spend like half an hour and die during the play, it does have option if you want to restart from the beginning or restart from checkpoint. (not sure the checkpoint thing can be done during non-story mode or not). So far didn't find the reviewer here mention about it.
