The fourth Super Robot Wars (SRW) represents a modest increase in complexity from previous titles, with additions such as a customizable hero pilot whose choice of robot affects the plot, special pilot abilities, equippable robot parts, hidden items on the map, more seishins, and new stats like crit rate and robot size. You can now choose reactions to enemy attacks during the enemy phase, adding depth and requiring more complex strategies. However, the game's balance is compromised by overly powerful attacks and seishins, making the late game too easy. Despite some UI improvements, the game suffers from a dark color palette and excessive seishin spamming. Ultimately, while solid, the fourth SRW lacks balance between its new features and the game's challenge.
