If you are familiar with the Fallout series, you will already be familiar with how Lionheart plays. If not, know the following... The game is a combat oriented, hack-n-slash RPG,
with an extensive character creation system (complete with alterable
statistics, traits, perks, appearances, etc), a deep linear story
(approximated at around 40 to 60 game hours long) and over 100 quests
spanning 80 levels. Combat is carried out through a simple point and
click interface (ala Diablo) and skill/stat management is easy and
straightforward (especially when compared to Black Isle's D&D based
games, Baldur's Gate and Icewind Dale), so newcomers shouldn't have
much trouble acclimating to the game's style.
I love you guys at IGN, you make this so easy for me. So, Fallout was a combat oriented, Hack'n'Slash RPG? Well, if Lionheart is a "combat oriented, hack'n'slash" like Fallout was, that's good to hear, because Fallout wasn't one.
Also of note, they credit nearly everything about the game to BIS with no mention of the game's actual developers, Reflexive.
