Thanks Kreegan, I'll try and get the additional skill sentences into the game in the near future. The green skill sentences would be candidates for easy additional text as well. I.e. block, armour penetrations, etc. If you need a list of them let me know. The gladiators entering the arena could be cool. I wonder if it would be more interesting to somehow allow the player to choose their entrance from a collection of sentences or something like that which allows them to create a semi-custom intro. I've often wondered if players would be interested in somehow customizing the fight text themselves. Since the game is a text based game and doesn't offer all the nifty customizable options that other games have. The main issue I could see with this is quality control and foul language usage etc. A first step though would be canned intros like you are creating.
EDIT: Here are the green sentence categories right now:
Block = A shimmering field of blue light surrounds GLADIATOR2's armour!
Armour Penetration = GLADIATOR1's weapon screams as it bites deep!
Kill = An ominous column of red and black mist shoots down upon { GLADIATOR1 }!
Life Protection = A brilliant golden light surrounds { GLADIATOR1 }!
