I will keep this short, I love this game and like to play it today (2015-11) and I loved to play it back in the nineties. It is what I would call a timeless classic. It is still as much fun as it used to be. You don't need to dedicate yourself to playing this game, it's fun for 15 minutes, and it's fun for 6 hours straight. You can leave and come back later with no problems getting in to it again. I have played other Heroes titles and this is by far the best one to me. Also Heroes 1 and 2 is fun, but the later installements in the series didn't quite catch my liking - unsure why that is. I like games like Civilizations, The Settlers 2, Imperialism, Age of Empires, Ceasar 1-2-3, Knights and Merchants and various simulation and RTS games. I have also played alot of RPG's etc but i don't think that is relevant to the genre. If you like any of the games listed above you are likely to LOVE this game.
