Throughout history the use of a spear and a shield was one of the most used weapon combinations. It was not only cheap, but also higly efficient. If it wasn't, then it wouldn't have been used for thousands of years.
Despite all that, the majority of computer games and Table Top RPGs that includes both shields and spears in the game, they always put in some stupid restriction or limitation that prevents this use of History's favourite.
This might be quite niche, but I would very much like it if Project Eternity is the first cRPG where I can fully employ this time honored fighting tradition to one of the characters.
