I feel like I should mention a few games here.
First of all, the magical chest system in the Resident Evil series. I don’t think it’s poorly implemented, really, because it certainly doesn’t detract from the enjoyment of the game. However, conceptually it is quite bizarre. Anyone who has played these games will know exactly what I mean, but for those who haven’t, here goes: you have a limited number of inventory slots, and you can store items in special wooden chests that are scattered throughout the game. The thing is, when you put something in one chest, you can get that same item out of all of the chests. That means that if you put a box of shotgun shells in the chest in one area of the game (say, a guest room in a mansion) you can get those same shells out of the chest located in an underground laboratory. It completely defies logic and reason, but interestingly it doesn’t take away from the experience of the game.
Resident Evil 4 did away with this chest system but introduced another ridiculous concept, and this one was much more poorly implemented. There is a hooded, cloaked merchant that appears all throughout the course of the game, in all the different areas. He sells you weapons, and can also buy items from you. We are to believe that this merchant follows you around all over the entire game - and, also, that the zombies, evil monsters, and religious cultists who populate the game areas are just fine with this merchant setting up shop in their backyard. The Merchant has a British accent, and speaks the same stock phrases to you every single time you talk to him, which is very annoying and detracts from the realism. (Don’t get me started with the “realism” of zombies and monsters, you know that isn’t what I mean - even within the realm of fantasy, character interaction should still be realistic.) Another annoying thing is that the Merchant can sell you every gun under the sun, but no ammunition for anything. Overall I loved this game but this was one of the cheesier elements of it.
Last but not least, one of my favorite PS2 games, The Getaway. This game was outstanding in many ways. It captured the look and feel of London very well. It had great cinematic cutscenes, professional voice acting, and a captivating story. The graphics were extremely high quality for the time, and all the cars in the game are real (as opposed to the goofy made-up cars in the GTA games.) I still play this game all the time and I have had it for half a decade. But there is one element of it which is problematic. There is no GTA-style map - you have to find your way around the game by following your car’s turn signals, which are supposed to tell you where to turn. But frequently, they will tell you to turn left, for instance, and then once you do that tell you to turn right immediately, or you’ll come to a “T” in the road and neither signal will flash, for some odd reason. Some people complained of the camera and the gunfighting, but I didn’t have any issues with those - my only complaint is with the driving glitches. But I love the game so much anyway I don’t let it get to me - it gets way more right than it does wrong.
