I don't like the upgrade system on ME2 & 3 for the Normandy, weapons, and tech. The technology looks primitive, it seems like BioWare half-assed on that, wires all over inside the Normandy, elevators instead of the teleporters, no state of the art cutting edge technology, and glass on ships instead of using force fields like in Star Trek. Also the side/combat missions are pretty much boring they show no realistic elements of combat missions like using real life tactics of guerilla warfare, advanced enemy AI, no connection to the main story like Witcher 3, and no military style how to execute missions such as stealth, setting up ambushes, etc. I think that if they're going to do TPS they should introduce tactical shooter elements to have players use their heads, instead of just going guns blazing all the time and to make it fun and challenging.
