dapHeroes is a mod I made to play with my friends (whose initials are indeed d, a, and p).
However, perhaps other people would like it. So, here it is:

Features:
- based on v1.51 (17389) version
- bounce mod
- it is compatible with regular game characters
- the creatures are always the six-players-version ones
- the difficulty formulae assume 5 extra players (ie, numberOfPlayers has been replaced with numberOfPlayers+5)
- yellow items are now white
- more enemies, but no triple bosses
- three versions, d, a, and p. All versions have extra monsters, but the "d" version fewer, "p" a bit more, and the "a" is the most extreme
- heroes and champions are more common
- camera zooms farther
- repeated boss chests are identical to regular ones
- experience faster
- rare items are less rare
- all suffixes and prefixes are visible
- all meta markers are invisible
- Ragnarok should be compatible, but it is untested as I do not own it. So caveat emptor.
- this is tentatively the final version; I may still update with new Titan Quest versions come out or to do bug fixing. Or, who knows, I get new ideas.

Of course, comments or constructive criticism are most welcome.

The pictures show the game with the "a" variant and the "d" variant, the "p" would be between the two. The same place in vanilla is also shown for comparison.

Update, removed the bosses from all difficulty levels. Even if toned down, their powers are overwhelming in Normal difficulty.
