To review.
Game is fun as hell. A successor to SR3. and really, if you were concerned that this was just a glorified DLC... You... would not really be wrong. Its an expansion more then an entirely new game. that doesn't really hurt the game much though. There is a ton of new content. enough to easily justify the price.
SR1 and 2 vs sr3. Despite some attempts to market the return of characters, and acknowledging the more serious tone in 1 and 2. 4 is even more outlandish then 3. I would say its dropped all pretense, and gone full parody. If I were being cruel I would probably compare it most to Scary movie. It comes dangerously close to "references are not jokes" territory. that said, I think it stays just shy, and at no point have I found the jokes and references to be tiresome.
Activities I have found more enjoyable so far. SR3 quickly got to the point of tedious on more then a few. Climbing towers in this one is pretty dumb, and should have been cut imho.
TK mayhem, should have been more involved. "throw alien wrecking balls" Now, I don't know if I am doing it "wrong". but throwing didnt work so well for me. What did work? playing katamari. holding the ball, running over people to build up multiplier, then running into cars. (too fast, and they blow up, knocking you down. although getting no ragdoll, etc probably solves that)
now, either they didnt even THINK of that. and missed out. or did, and didn't embrace what could have been amazing to run around and do.
Pacing on them does seem better though. Your homies send you out to complete "side quests", which 90% of them are just sending you out to do the random activities. If already done, they just auto-complete.
As I noted earlier. I think superspeed and jump shouldn't have been given so early. again, cars, and planes are almost pointless. it feels weird. and as if legacy from DLC. as if, the planned on giving you these powers in the DLC right away, because you had just played SR3 and wanted them right away of course.
