Languages are never fun in tabletop roleplaying games. People have come up with numerous ways to handle them, and their methods become especially absurd in games where languages are handled by leveled skill points ("Sorry, professor, but I can't learn Spanish until I go shank some goblins and steal their loot."). LotFP has a linguistic skill, for example, that you roll to determine whether or not you know a language; max the skill and you know everything. AD&D had "alignment languages" and people the first part of that term was even worse than the second. Some effort has been made to at least make the languages interesting. Meanwhile, most people just dispense with languages entirely. Here's a proposal.
