In my mind Watching a game where you lead by one goal is probably the more intense one, especially if its the playoffs or a big game you know, the one thing you dont want to see is your player be the reason the game gets tied because of a bad giveaway, or a missed shot leading to a breakaway going the other way. Its especially heartbreaking if you have a lead like that for a long period of time, then suddenly its tied and boom, 2 minutes later the opponents get another one and game over, just like that. But watching games where you desperately need that tying goal is also a lot of fun and can be nerve wrecking at times. I think the most tense for me was back maybe 20 or so seasons ago, when i was on the Platoon and we were in the finals, just watching a cup winning game, it felt amazing, especially cause we ended up winning the game and the cup!
