Yeah, it's tough to review games like this one. Frogwares' first, the game with which they started their succesful SH series, so of some minor "historical" value for the genre - and yet a letdown in most ways... Released in 2002, this game looks dated even for that year. Looking around might be smooth, but moving is clunky, and sometimes an exercise in pixel hunting, which is hardly a recommendation... Inventory management is annoying and slow, and (unless I'm mistaken) no usage of keyboard doesn't help.
The setting is, yeah, SH meets Egypt (with a bunch of other clichéd influences & touches), quite uninspired, as is, more or less, the story (Doyle was likely turning in his grave because of this one), along with voice acting, which goes from "so bad it's good" to "meh"... Sherlock himself, apart from being a Frankenstein of Sherlock clichés has "accent issues", failing to convince or interest. Music? I was just playing Transport Tycoon Deluxe before this, and the quality is eerily similar at some points... I honestly didn't expect almost midi level music in a commercial (if budget) 2002 game.
So, OK, there are all too often great adventure games hidden behind an unimpressive technical side. Is it here too? No. The puzzles are (so far, I only got to the beginning of the 4th chapter) as uninspiring as they can be. Generic slider puzzles? Check. The "5l and 3l buckets & you need 4l" puzzle? Check... Illogical / obscure solutions? Check. Poor & simple puzzles have likely been obscured by, in some cases, a complete lack of hints on what you're supposed to achieve, some backtracking, and extreme pixelhunting in a 360 environment, requiring from you, sometimes, to go from place to place and pass your cursor everywhere in hope it changes. And timed puzzles... They are a personal peeve of mine, but they're quite badly and annoyingly exectuted. Like someone figured it was damn too easy on its own, wasn't capable of creating interesting puzzles and just made it harder by making it more annoying.
Basically, it's a dated, generic, dull first person adventure game. It's amazing how much Frogwares have grown and improved since then... but this one you should avoid unless you're a completist & hardcore Sherlock Holmes fan.
