I'm disappointed with Tennis Aces' offline offerings. Adventure mode is a far cry from the kind of story-driven single-player modes offered in previous games (GBA/GBC versions) and is over very quickly - I cleared all of it in 3 hours. Similarly, single-player Tournament mode is very flimsy - 3 quick tournaments which I did in about 45 minutes. The lack of options and lack of a proper course select offline is also disappointing, and I find the music is seriously bland. In Mario Power Tennis on GameCube, there were 8 different tournaments with different rules and courts, which offered far more single-player value than Aces does. Sticking to either tiebreakers or two games/two Sets makes sense online, where you don't want games against strangers to go on indefinitely, but restricting options in the offline modes makes no sense to me. It would be very, very easy to give players more options in these modes - as well as a proper court select screen and further single-player (or local multiplayer) tournaments. It feels like they've cut corners.
I'm going to give online and local multiplayer a go over the next two or three weeks, but right now I'm worried Aces isn't going to have much long-term value for me and I might end up trading it in or selling it on eBay. It doesn't feel like it should command a £49.99 price-tag at all. While there's an obvious focus on online, even the online options are very limited - it's a far-cry from having say, half a dozen competitive and one co-operative mode on Splatoon 2's online, or several battle modes plus 48 tracks for racing on Kart 8 DX. I think mechanically the game is solid, and the range of characters good - but I hope Camelot patch in more options so I've got more varied choices when I'm offline or playing locally with friends.
