Some hints for my upcoming games:
And oh, I overlooked #47 and forgot to give an additional hint. Hmm.
#47: The game series includes character from different games, including games from other companies.
47 is Super Smash Bros Brawl
As guessed correctly by Liquid Laser my game #47 is Super Smash Brawl for Wii. It was my first Smash, maybe it is for that I like it so much.
Well, Super Smash Bros is a great fighting game in each iteration. Brawl offered an interesting roster, many modes and just a lot of fun. Like other Sakurai-games too Smash has achievements, and they are so well implemented, that I wish the platform would offer achievements like this.
