Given how popular Halo is, it's no surprise that the series has enjoyed its fair share of spinoffs. One such title is Halo Wars, an RTS-themed game where players must tackle a wealth of missions as they build bases and use their powerful units to take out enemies with a fair bit of preparation. The strategy elements of this title may ring a bit hollow for players, but Halo Wars more than makes up for it with stellar cinematics, a fun story, and an excellent interpretation of the Halo universe that adds some much-needed credence to this IP. The fact that the studio behind Age of Empires 4 worked on this title makes Halo Wars an easy recommendation for these fans.
