These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Ensemble Darkhorse — Seseri keeps getting brought back, and is playable in Espgaluda II Black Label, because of her popularity
Polished Port — Espgaluda II's iPhone port is well-received, and is said by some to show that the iPhone is very capable of handling "hardcore" games. Although Your Mileage May Vary depending on whether you like playing precision-demanding games on a touchscreen.
Sequel Displacement — Espgaluda II, particularly in North America, thanks to the region-free Xbox 360 port and the iPhone port, the latter of which was officially released in in the US.
Surprisingly Improved Sequel: The first game felt like a really cheap cash-in on the "ESP" name with an art style that took some getting used to as well as unsatisfying graphics for the shots. The second game was much more fleshed out and had much more interesting and detailed artwork.
