Interactive Gameplay

I am well versed with games that change based on the decisions you use.  I can think of Mass Effect, Oblivion, and the Final Fantasy series to name a few of the better ones.  These have so many different choices, like the type of character you use, what sorts of skills you develop, and my favorite choice, if you're good or evil.  I tend to almost always gravitate to good for some reason, must be the Army streak in me.  The best of all of those is Mass Effect though.  They were able to create a unique situation where you can develop your character and take him with you through all three games they released over the years.  This has been revolutionary for the industry, and I'm sure will start to be the standard soon.  Even the MLB game that Playstation has is adopting this for their franchise player mode, where you will be able to use him on both the Playstation and their portable gaming system.
