Bush Race- Pretty basic, and easy in my opinion
Chance- Everyone has same amount of possibility of winning, won 3-4 times.
Freeze Tag- Unique in iClassic Server and winning requires teamwork with random players.  
Hide and Seek- Very entertaining, but simple hints just ruins the fun. Hints that makes you think, gives you more motivation.
Horse Race- The same track gets old and too familiar now. Think I win the most horse races.
Ice Race- Hard mode is easy for me, while Easy mode is hard. Gives you the rush when you could fall in the water at any time.
Juggernaut- Depends how the Staff host it, if they're using max health and running at maximum speed where you only see a blink of their avatar running through players, its just plain luck now.
Sumo- Very amusing. Sad they don't use the event anymore.
Spar- FUN.
Survivor- It's all about who has most potions, and how well they maintain their health points. 
Treasure Hunt- Gives you the thrill when you find a chest out of everyone else in the crowd.
Trivia- All about knowledge you know before hand, you're the fastest typer using Google, or plain lucky guess.
Missing: 
Jump and Run- This event captures my attention because they made a new keypad format for it.
Matt's events- The best events to me, using players to help with the events. Ex: Leader of a tower at the time, such as Sardon, let's Matt host a "juggernaut" using the tower. There would be at least 50 players crowded in the halls trying to get to the roof. (He has many more events)
Chris's events- He makes his own events sometimes inside his guild house. It's a "you had to be there" situation to know what I'm talking about.
Warrlordd's Marathon: Best way of hosting Treasure Hunt for everyone.
There are so many more events I haven't listed, but these are the ones I remember at this moment.
