I actually got the platinum for it (or all the trophies) when I first played it back on PS3, but enh. Playing it again on PC, I couldn't help, but be bothered by how much was wrong with it. So damn much is totally half-baked in that game. The shooting, the level design, the melee combat, the perk system, and, yes, most certainly the stealth. Big time.
If it weren't for how awful & pathetic the stealth was, along with the infuriating mini-games associated with lockpicking & hacking in which failing them leads to an immediate alarm going off, then I probably would've found the game to be somewhat more enjoyable, in closer comparison to how I felt the first time I played it.
In my case, I never encountered any glitches with the game, whether it was on PS3 way back when, or PC relatively recently, but, even so, AP was mostly a chore to play & finish. Patching out glitches is one thing, but it's certainly a shame how Obsidian couldn't patch out how lame & half-baked all the various mechanics in that game were and that was really the larger blemish on it, frankly, as opposed to any glitches it had at launch.
To be honest, it really bummed me out how very little from that game actually held up for me, when I remember it being so comfy to play all those years ago. Even the story & main character just got on my nerves & were both boring as hell. Granted, I played in a very wishy washy way, sometimes being aggressive, sometimes being a nice guy, usually doing the opposite of what I really wanted to do, which I also feel somewhat hampered my enjoyment of everything. Despite that, something about it all just felt super tedious and a lot less interesting/satisfying than I recall it being originally.
Anyway, the original Mass Effect is another game that didn't hold up for me. At all.
I recall posting my thoughts & reasons for that before, which you can find here >>>/games/44603
, so it's easier to just do that instead of writing it all out again.
