So far it's been a pretty good tool for learning bass.
The actual teaching elements of the game are kind of barebones, even the guitarcade stuff isn't great for learning but it's a fun distraction. Learn a song and Session mode are really where most of the experience comes from. My biggest problem when I first picked up guitar was mostly a lack of interest but RS14 provides me with a constant set of goals and a pretty decent library of tracks to keep pushing through with bass, unofficial listings make that playlist even bigger and more to my taste too. The ability to customise tones is fantastic too, it's not the same as investing in waa peddles, cabinets and heads, but it's as close to Dan Maine's set up as I'm going to get. The riff repeater and dynamic difficulty are key to what makes this such a good learning tool, being able to isolate a specific part of a song and slow it down and repeat it over and over without loading screens or fluff makes it easy to correct mistakes. I think most of my time in this game comes from 2/3 hours doing the same 20 - 30 seconds of a song over and over.
Only negatives are that the Realtone cable is actually pretty difficult to come by now and it's still really expensive, also DLC is quite expensive too. It's not bad when you consider you're getting a high quality, licensed song broken down into a format with dynamic difficulty but they always become dirt cheap during sales and it's kind of annoying to wait for that window. The tuner isn't always as precise as it could be and sometimes lower notes and especially chords don't register but it happens infrequent enough that it's forgiveable.
Just finished me session with stonesour i kicked butt (well in my mind i did), where else are you gonna get to play along with some great bands and learn as you go along, forget your 4 button plastic guitar and plug in the real thing and play.
9 out of 10 for this lost a point because i think the graphics need a polish
Great game. I have played Guitar/Bass for 13+ years so I can't say how well it helps teach beginner's, but I think it's fantastic if you want to learn some songs you probaly wouldn't go out of your way to learn. If you have a audio interface I would recommend running the game through NoCableLauncer as the official cable is hit and miss. Also if you have experience with tabs, invert the strings in the options.
I was already a pretty well seasoned guitar player before I ever played any of the Rocksmith games, but I've still poured hundreds of hours into the 2014 edition and several into the previous one as well, just because they're fun! I can't really speak to how well they function as a general teaching tool (I haven't really looked into the technique lessons or anything like that, so I can't really comment on them one way or another), but they're definitely a fun way to learn some new songs. I'd highly recommend this game for anyone who already knows their way around the guitar a little bit and who just wants a fun, music-based game that involves real world skills, or for anyone who wants to learn some covers!
Pros: A lot of fun, an extensive library with a pretty good range of genres and a BUNCH of DLC songs, fun minigames, a great 1/4 inch - USB peripheral (though you'd obviously have to get that online somewhere if you're just getting the Steam version)
Cons: May not be a perfect teacher, if you're looking to learn how to play in general then a real life guitar instructor would probably be a much better choice. Can be finicky on giving you credit for certain things, you kinda have to play EXACTLY how the game wants. I never really get credit for any of the bends because I don't bend the absolute hell out of my strings, or sometimes it doesn't give you credit for hitting certain chords if it doesn't properly detect every single note involved in the chord, even if you're playing it correctly. Be wary of that. The input gain is fine for my guitars, but my bass is unreasonably quiet no matter how I adjust the settings, but it's also a really crappy bass so that might just be the instrument.
Side note, not really a con: I wish there were a way for the game to just pitch shift the songs that weren't recorded in A440 into their respective tuning. I'm fine with tuning down to drop D or DADGAD or weird Radiohead tunings or whatever, that's not what I mean. It's obnoxious when a particular song was originally recorded SLIGHTLY sharp or SLIGHTLY flat (like A451 or A438) and the game makes you tune all of your strings slightly sharp/flat as well if you want to play it. It's a shame because that prevents me from buying some DLC songs that I otherwise would really want. It's just not really worth the hassle.
