I just thought Jericho could have been an amazing game. I won't say it sucks, but it's definitely not what I would call "amazing". The premise was fine, the action was good-albeit repetitive, the powers were unique and for the most part helpful...but it was all marred in the way they went about it. Also, it didn't help that each of your team members would die within the first 5 seconds of a skirmish and you would spend your whole time trying to run from one body to the next to just revive them while you're under attack.
More recently, the new Lord Of The Rings game. It could have been as awesome as Battlefront and Battlefront 2. Instead it was outright terrible.
