Really great, until after castle 3
First, let me say that this is a very, very well-made game! The RPG elements and faction system were nice. It was very fun, up until castle 3. Explanation as follows:
I played through and did every side-quest for my factions up through the third castle. And then suddenly the arches guarding the bridge were *way* stronger than me. So I had to spend a bunch of time clicky-click-click leveling (which is repetitive and not-fun). After I was powerful enough, I did all the quests available to me and got the best gear I could... and discovered that I didn't have enough reputation to do the next quests. I'd thought I'd missed a whole section after castle 3 or something, so I double-checked, but no. Since I'd already done all of the quests for those factions I had to sit there and kill *hundreds* of lame enemies to get the hundreds of reputation points I needed (which is *also* repetitive and not-fun). I know that you wanted the game to be long, but making me spend hours gaining street-cred is a cheap way to do it. =/ And of course, after killing 100 gladiators to get the 500 points I needed with the tracker's, I was rewarded with my quest... of killing 30 more gladiators ><
All in all, I had a really great time until the game got super-repetitive. I was very impressed with the quality of the game, and would love to see more good work from you. Keep up the good work!
Oh, and there also seems to be a glitch involving the river surrounding the first castle. I was on the lower-right corner and saw what looked like a bridge and I somehow fell into the river. I thought this was a feature, until I realized that I couldn't get out of the river and couldn't shoot anyone (I was a ranger) and they couldn't kill me to get me to respawn. I wandered off the north end of the map, which crashed Firefox. =/
