Quinn, I did the same thing.
I got to some of the few mission and I put Shadow Tactics down for most of a year. I found that some of the last few missions were getting complex and the developers were presenting you with fewer numbers of ways to get past certain areas.
I eventually hundred percent-ed the complete game collecting all the badges. The speed-running of some of the missions was tricky and I needed hints from others doing speedruns.
Shadow Tactics was an excellent game overall though – I am going to savor Desperados III. I will get my money out of it.
I find it strange that the original isometric stealth games like the original Commandos and the Desperado series were made ~15 to 20 years ago…
Commandos 2 was a classic which was loved by so many. I don’t why there was a gap of a dozen years before Shadow Tactics.
You would have thought that someone would have picked up the genre during those more than a dozen years…
