Yes, it was underpowered relative to its purpose in 2012. Nintendo designed it as a device that was supposed to bridge core gamers and casuals, but it was in no position to support the games that were to come in 2 years time. Developers didn't bother with it even when they were making 360/PS4 cross gen games because unlike the 360 it lacked a user base and unlike the PS4 it lacked a future. Not having PS4/X1 games wouldn't be that bad if it had a successful gimmick to fall back on but it didn't, Wii U sales were never good post launch month.
