That sounds like something right up my alley.

After Valhalla, that actually sounds great. Fighting has never been the charm of the series to me, and Valhalla was possibly the most disappointing game of the series from that point of view - even though it made sense considering the theme. Another massive problem was that Valhalla was way too large. I would probably have been fairly happy with the game had it been half its actual length, but soon after halfway, I started to grow weary with the game, and when I finally completed the game, I don't think I've ever been as relieved to complete a game before. Stealth and smaller scope sound very good for the series. That said, at the same time I'm also worried it's not going to be treated with enough respect.

I haven't played Valhalla nor know who that Basim is supposed to be, but I'm currently playing AC Unity (what a tedious game!) and, while playing it, I've actually thought a couple times how the game could have been much better if it had a bigger focus on stealth.

So yeah, like the other two above me, an AC game with a bigger focus on stealth could actually be quite good.
