And what if you like the games, even if they are so similar?
Then that's your personal taste and that's fine, but it doesn't change my opinion of the games at all.
Right now, I'm playing through every single LEGO Tt Game on Steam to determine how the franchise is going.
If you go to this link and filter by "LEGO", you'll see my progress (slow, but getting there). I'm having great difficulty finding the differences between the games. Yeah, there's some minor polish and tweaks and newer titles, and some of the activities change, but ultimately the game mechanics are:
->Primary Attack (out of 5 categories, melee, sword-melee, ranged weapon, magic, zapper)
->Context Sensitive (anything from using the force, opening a panel, building etc)
->Ride Vehicles
That's the entire list, and it's become excruciating over just how many repetitive actions are required to beat the level. Each level is just a Tt designer following a checklist, rather than doing any kind of actual design ("Okay, I need to add a force puzzle here, and then I need a co-op force puzzle somewhere else, and a blaster puzzle here..."). Hell, I'd rather play a Mario title, would they be released for Steam. It gets even worse when you add in Tt's stuffty enemy system and their even stuffter "run towards the camera" segments.
What makes a game fun is challenge, something the new LEGO games lack completely. The old LEGO games were vastly different, and even though there was some hand-holding (Stunt Racers completed the "orange test"), if you play a game like Racers or Rock Raiders, you actually need to get better and work at winning, whereas a Tt game just expects that you just keep playing the same tedious puzzles over and over again. Time devotion != challenge.
I mean, I like Assassin's Creed too, even though I can tell that there isn't an overly significant difference in gameplay between the first game and the latest.
I'm not saying AC is any better than the LEGO adaptational games. All I'm saying is that people shine different lights on them when they are just as guilty of each other of repeating the same gameplay mistakes over and over and over and over and over and over.
