I really do agree with the disappointment many of you are sharing. I feel it very keenly as really gardening was the one skill I did with all my sims, it was enjoyable, stress-free and actually I found the whole process of getting a full garden to Perfect as the one aspect of the game I looked forward to doing.
Currently I am quite at a loss in my game. I have no real desire to play as now that gardening has become so stressful I just can't bring myself to bother playing. I still have the evolving bug so none of my plants evolve nor really need tending, obviously splicing is now a hit and miss with me getting a 'miss' every time. I loath the way the plants Out-of-Season look but planting everything in a glasshouse isn't ideal as plants do seem to grow much slower when they are shelter. (Or maybe this is just another bug I am experiencing.)
I didn't realize until all theses changes that I basically play TS4 as a gardening simulator! I suppose having played through every career and every dlc 'career' (restaurants, retail, vet etc) so many times and having completed every aspirations multiple times that gardening was the one area left of the game that I genuinely enjoyed.
I miss seeing my sims watering, weeding and evolving each plant. Instead now they water all, weed an area and then evolve plants from their bathroom while having a shower now that is an instant interaction that requires no input (no animation) from a sim. Instead I watching my sims Research Plant over and over and over again, performing this interaction on the same plant as there is no other way to really level up their gardening skill now that the plants need so little care. They also prune and shape bonsai but I have never found that fun.
It's difficult to look at the changes to gardening objectively. Had everything else been left as it was possibly I would find the chance element of splicing fun... but on top of all the changes and the bugs, well... *shrug* I give in really. tbh I've been playing through my games in my Steam Library and have no real desire to open Origin.
I also have to gripe about the weather in Seasons. I've now played 3 different save files from Spring to Winter and in all every day in Spring and Summer were either very cloudy or rainy. I'm quite sick and tired of grey depressing days in my game to the point where it is irritating me and I really find it all quite depressing to look at. I realize I can employ cheats (thanks to Twistedmexi), live in Oasis Springs or use the weather controller object but my point is...every single day during spring and summer as non-sunny days?
All this coupled to the gardening changes/bugs..well... No thanks, I'd rather play anything else as TS4 simply just isn't fun for me at all anymore.
