Why play this one? LEMME TELL YOU (courtesy of the SA Forums):
For one a lack of consumable hoarding. The Tome philosophy is that hoarding potions and scrolls until the end of the game is neither fun nor particularly easy to balance. Things generally handled by consumables like healing and teleportation are handled through runes and infusions instead, which are basically swappable talents. Likewise Tome dungeons do not respawn. Once an area is cleared it’s generally cleared for good. The game’s leveling and xp system is balanced around these concepts so the player should never feel the need to grind to advance.
Tome also comes with a full tile set, has sound and music, as well as an integrated chat system so you can ask advice of other players without leaving the game (hence the thread title). It also supports ASCII and has an options menu so almost any feature you don’t enjoy you can turn off.
There’s more, the game’s pretty innovative and it would be hard for me to cover everything. But briefly, a friendly interface that supports both keyboard and mouse based play along with fully functional auto-explore, a fairly unique combat system, a polished UI (which will be customizable next beta), a very active developer (the game’s seen 37 beta releases in the last two years), and a growing player base.
Plus… it’s pretty.
