well agricola is like a peaceful RPG. you are a farmer in the 17th century and have to survive and maybe become wealthy and raise a family. sounds weird, but its so much strategy in it. very deep game and can be played solitaire as well.
talisman is a classic RPG game. typical fantasy, you can choose between 14 different characters, which are quite unique. a high luck factor in it, but you never really notice it. slaying monsters, collecting treasures, fighting other players. talisman has it all
saratoga looks like hardcore strategy...
shark looks very interesting...
