Right now, I'm playing through with FCOM and enjoying it very much. I used to be a OOO+MMM man myself, but I really loved some of the features Fran's had compared to OOO and I really wished I could put them in someway. Then I found out about FCOM and I've been happier ever since. Also added WarCry into the equation, as I was really into Diablo the first time I started playing with it. I skipped on Bob's Armory though. Thinking about doing T.I.E. Integration, but I don't know if it would be worth it or not. Anyone have any comments on that?
I do TIE-In + FCOM, and I love it. It makes the game really hard at the low levels (you have to be very careful where you go), and you end up fighting lots of goblins, but you come into your own about L10 (meaning you won't get beaten down by bandits and raiders, not that you can tramp all over the landscape and kill everything). I played to around L25 with my last PC before the saves got corrupted, and I never got bored for lack of a challenge. Oblivion gates were plenty challenging, and there was still lots of stuff out there that was more than happy to kick my butt for me.
My current characters is L11 now, and I'm still wearing magical leather and chainmail armor, with a magic mithril shield - I simply haven't found anything better, besides a glass cuirass with chameleon (and I hate chameleon). With all the quest mods I've got, I expect to be active well into my 30s, maybe even to 40. I've never gotten above L34...
Too bad TIE is not modular. It has so many things I like, but also many things I don't like...
Yeah.TIE-In is a little less tweaked; fortunately, there were only a few things I didn't like and I could change them myself (repair hammers weighing 4 pounds?!).
