I have played many cRPG"s since the days of Baldur's Gate and Fallout. More often than not these are very fun games. Every once in a while an incredibly well designed game comes out and manages to balance all aspects from writing and narrative to gameplay marvelously. This is the case with games that become the measuring stick of a generation, such as Baldur's Gate 2 and Pillars of Eternity. Rarely do we get to experience truly special cRPG's that while imperfect, push the envelop of traditional media and defy our expectations of games and literature, and simply sit at the far end of that measuring stick. This was the case once with Planescape: Torment, a unique game with thoughtful narrative, high quality writing and elaborate RP-mechanics. I suggest we name Tyranny the PS:T of our generation: it has the most unique mythology we've seen in games in years, the writing is excellent, the RP-mechanics are deeply fleshed out, the world truly responds to our choices and actions, and, despite not being a very long game (40ish hours), it manages to deliver a true literary experience rarely found in cRPG's anymore.
If you like any of these things, you should most definitely play Tyranny. It is a shame we don't get many games like these anymore but here's hoping Obsidian will be *allowed* (by their new corporate overlords) to release excellent, thoughtful games like these in the future, even if they don't appeal to a wide crowd.
