This is a list of Large IGMs (IGMs that would take more than 5/10 minutes a day to play) that are good to excellent.

Banda's Boardinghouse of Vanadia1.50Gregory Campbell$10 Large Random Events IGM. Pretty well done, a lot of new things. The cock fighting is pretty cool, and a lot of the events are done well too. Some bland things, but mainly a good random events IGM.
Castle Coldrake1.1BChris Fisher$10 Random Events IGM with a flair. Fascinating descriptions, everything seems different, and new. Not too modifying (a bit, but not too much). Annoying Beep is NOT in this version.
Caves of Despair1.01Jeff Fanjoy$3 Fascinating walk-around/forest fight IGM. Tons of events, even with 20 minutes in one area, I felt I'd only scratched the surface. The PERFECT addition to your Lord game! Default to Expert prompts problem fixed. A wonderful alternative to the forest!
Daemonica3.0Children of Galeaxy$5 Large Buy/Sell Random Events IGM. Surprisingly well written, although still too modifying for tight competition. The best Buy/Sell/Forest Fight/Random Events IGM I've ever seen. Looks great, feels good, decent descriptions. A bit confusing, but that can be a good thing!
Dragon's Claw Tavern2.01Brian May$5 A Bar/Inn IGM. Great "tavern" feeling in this IGM. A couple flaws exist, mainly in attacking the wandering warriors repeatedly with skills. However, it's probably the best Bar/Inn IGM out there. Great for casual games, not that great for heavy competition.
Fat Man's Misery1.04aJohn A. Tucker$12 Fat Man's Misery is an IGM that will take you into a Valley filled with surprises. It's humorous, looks good, and is very interesting. Lots of new ideas incorporated, and not ov modifying. A bit expensive, but a good choice, nonetheless.
Gypsy Camp of Vanadia1.50Gregory Campbell$10 Visit a Gypsy Camp and surrounding area. There's an ANSI knife contest that's pretty cool... And a search over a forest/cave terrain. This is really great, but it's a large pain traversing the caves the way it's designed, although leaving the cave is pretty easy (smash a gem). Only slightly modifying through fights.
Hidden Forests1.50Gregory Campbell$10 Very well written exploring IGM! Good ANSI games, nice complex setup. However, it gives way too much in the way of rewards, and is quite time-consuming. Might be better off by itself (if you run it as an IGM).
Jadov1.60Dan Buckler$10 A LORD inside LORD. Deja VuDoo skills are pretty darn cool, and the town itself is nice. It's a bit too giving, not all of it is completed, but it's turned into a pretty nice IGM (the price drop helped). Overall, Jadov is large, and if that's what you're looking for, try it!
Kaldor's Court2.0Chris Fisher$2 Random Events / Buy-Sell IGM. Pretty interesting events, selling done nicely. A bit too modifying. Good implementation of event ideas.
Land of Merdiqua1.1John Gibbard$8 Extremely funny large IGM. Buy numerous different weapons & armor, each has its very own description & class. Visit weird personalities, attack sun-baked bathers, get lost in the forest, and just mess around. This IGM doesn't seem to have too much effect on the LORD game either! Enjoy!
Latrine3.02Vamsi TadepalliMAIL Funny and sick IGM about a bathroom. Extra fights make it a bit too modifying, but it's sysop-configurable. Great for teen/pre-teen games.
Lord Cavern1.3eJason Brown$5 Random Events IGM. Very interesting descriptions, quite fun to play. Not very modifying. A VERY new twist on random events -- there's an EVENT PROGRAMMING LANGUAGE! FuN!
Lord Pit2.5Trevor Herndon$5 The Pit for Lord. Not realtime, though (you move, then the monster moves). Keys seem a bit weird. However, a brand new invention for an IGM. Worth a look.
Medieval Tournament of Vanadia1.50Gregory Campbell$10 Huge ANSI Action IGM. Wonderful events, not too modifying. Be warned, don't try this one without at LEAST a 14.4. A good pick for most games!
Mirror of Illusion2.1Joshua Eckerman$5 Travel to different LORD settings. Pretty cool... Not strict enough on giving, though. A nice, fresh, new IGM idea.
Moondust's County Fair4.07Nannette Thacker$10 Visit a fair, compete in the events. Not a true IGM; may not work properly multinode. Although games many look the same, they actually feel much different. This should be a hit with your users, but the install is one of the WORST I've ever seen -- good luck setting it up!
Zephyr's Town Square0.9aStephen Oberholtzer?? Amusing Town Square semi-spoof of Lord. "Hacker," a Seth Able clone spews forth funnier poetry than Seth. Other features are fairly common, and menu styles try to echo Lord, and sometimes succeed (and at other times look pretty bad). Good town square IGM.
