Cross Game, Diamond no Ace Recommendations
Both are about baseball and wanting to bring one's team to Koshien. Whereas Diamond no Ace is more about the sport and nothing but the sport, Cross Game brings a lot more to the table, such as drama and romance. Although I find both to be very enjoyable anime, Cross Game holds a special place in my heart...it is one of the best anime I have ever seen (go to my profile--I've seen A LOT of anime) and is definitely the best sports anime I've seen yet. If you like Diamond no Ace and baseball animes in general, you MUST watch Cross Game!
Cross Game and Diamond no Ace are anime series with a sports theme relating to baseball. The main male protagonist gets involved with the sport. Throughout both series, the main male protagonist trains himself to become better and earn a reputation.
There is competition in both series while also holding a degree of comedy.
They both also takes place in a school environment as the main characters meets both friends and rivals.
Ace of Diamond and Cross Game are both baseball-centred anime. Cross Game, however, features more romance and has more character drama.
Diamond no Ace is an improved version of Cross Game IMO, not because the story is similar, rather because it deals with similar themes (growing up, hardship, being away from loved ones) while presenting them in a much more polished manner.
The baseball aspect is also much better explained and dealt with in Diamond no Ace.
